(First off i don't own WoW and i only played Warcraft so i don't know the rest of the lore in WoW so if there is a problem or a missing lore then can't help you there but i will try to add as much lore as i know of.)
(The remake from The New Scenario of the Blood Elves to)The Rise of the Blood Elves: It began before the events of World of Warcraft and is set during the time of the Frozen Throne. The Blood Elves who used to be High Elves who were defeated so easily by the Scourge, most of the high elves were destroyed but those who survived fled Quel'Thalas and retreated out of Lordaeron to join the survivors to the west while those who were left behind fought against the Scourge while they flee. The Prince who was in Dalaran rallied his forces and moved to Lordaeron to find the rest of the elves, making them all become the Blood Elves who wish for vengeance over what Arthas has done but they couldn't defeat them here so they left Lordaeron and travelled to Dalaran where they know there's a resistance that is fighting against the Scourge there, there they can finally join the human survivors to become the New Alliance under the command of the Grand Marshal Garithos.
The outskirts of Dalaran lies a battlefield where the Undead have been trying to press through here; a mage from one of Garithos forces came through here in the ruins and notices the war is not going well as the dead have taken control of the island in the middle, the north side sector and the western area while the Blood Elves controls this east side and the south area trying to stop the dead from advancing.
The Blood Elven archers in the ruins fires out towards the undead archers on the island and they shoot back, they fire siege through the ruins while the archers are ducking and shooting back at them, ballista's being fired back and an undead ship was coming from the rear they would focus their fire on that ship before it gets in range. The mage would move out of there trying to find Prince Kael'Thas who could maybe be outside of these ruins leading the assault against the Undead.
As the mage walks through the ruins seeing some dead undead and elves, some wounded while their healers try to recover their wounds so they can rejoin back the fight, lucky for them there is a great fountain of life in these ruins and because of that the elves can replenish themselves and join back to the fight but those who are dead are dead. The mage finally got outside and notices a few fireballs coming down from the sky crashing to the ground in front of him but missed taking out anyone. The Blood Elves runs forward heading to the west there he will find elves battling against the undead and soon Kael would join the fight as he stands on the high ground looking over to a bridge that the Undead are using to get to their side, he channels a strong fire attack creating a strange symbol in the water underneath the bridge and would soon sends out a large fiery explosion taking out the undead on that bridge and destroying their way through here, with that the defenders raise their shields in a large line formation in front of the dead while he signals the archers behind the defenders to take aim and rain down fiery arrows down upon the undead on the other side.
The elves cheer in victory and would press forward getting closer to the destroyed bridge, their shields were still up and their archers behind them advanced forward, the rest of the forces would focus their fire on the dead on the island. Kael would walk back noticing a mage who has a light blue type colour on his cape knowing who he is.
"Prince Kael i see you have taken this area but it seems you have lost the battle on the island." He looks over seeing the dead controls the area; he did see a ballista fired towards it blasting one of their siege weapons to pieces.
"We will soon have control of this area. Our forces are rearmed and ready, we may have lost the island due to their flyers but we will get it back i promise you that."
"We shall see about that."
A female Blood Elf runs towards Kael and the mage along with two Blood Elf Lieutenants by her side. She had blonde long hair and black armour along with red robes covering a half of her body covering the left side of her chest and bottom that reaches close to the ground, high thighs armoured leggings and has four red daggers on her right side of her waist and holding a long sword on her right hand.
"My prince the ships are fully repaired and are waiting on your go."
Kael looks over to Alexis who was by his side during the retreating from Quel'Thalas, during this fight she has become second in command of this operation here "Good job Alexis." He looks at the mage "You may want to see this, i am sure Garithos would want you to describe the battle here." He looks out to the ocean to the north east.
Two large ships belong to the elves, armed and ready with cannons and archers on top deck. They move over the area heading to the island. "Get a signal for them to target the Undead in the north side."
"Understood my prince." She looks over to one of the elves holding two staffs that glow bright in red "Target the north side!"
The mage would look back to her then towards the ship, he raises his staffs and started to move them using this for communications from a far. The elf on the ship looks over seeing the signal knowing what it means, telling them to target the north and that is what they will do, both ships would turn their guns to the north along with the archers taking aim lighting their arrows on fire. Undead ground forces and a few of their buildings were on that side, once their ships got into position they open fired towards them, blasting their towers and forces before they had a chance to attack, the archers fired burning the undead and causing them to retreat to the west. One of the ships would turn its attention to the island causing the elves in the ruins to stop shooting and watch the scene as they fire towards them with five cannon ball shots along with their archers targeting the flyers before they got close, taking them down quickly, finally the undead were destrotyed removing them from the island giving the elves inside the ruins something to cheer for.
Kael smiles as they finally got the Undead on the retreat. "You should tell Garithos we have full control of this area. We have won."
"Very well i will notify Garithos as quickly as i can." He turns back and started running back.
Alexis would walk next to him still looking at the two ships that are moving towards their way to make a landing. "We won this fight my Prince, at least now we have gotten the action here instead of on the front lines."
"True but i do fear we will be dealing with more trouble from Garithos."
"I really don't like the way he talks to us and especially you milord."
"There is nothing you can do, and you can stop with the formal Alexis i am no longer the prince of my people."
"I know but you are a striking hope for us elves, why else are we fighting for? We are fighting for you and for Quel'Thalas."
"I know we still have a fighting chance." He looks to the side and walks towards the troops by the bridge "But we will have to be vigilant if we want to someday take Quel'Thalas again."
She nods and follows him looking out at the view seeing the dead are fleeing in fear if they even have fear inside of their minds but this battle is still on because the one in charge of this is indeed a Death Knight, watching the fight and preparing for another attack but the Death Knight would withdraw from the area with whats left of the undead forces to prepare something big.
One day went past and the Undead haven't attacked the elves and finally they got some rest and because of this the elves have secured an area on the island and on the north side for now, using the ships as their towers to make sure the dead don't advanced on their positions. Both Alexis and Kael stands in the ruins by a table of the map of the land he prepares a next strategy but then one of the elven workers would run over to the two telling him that the grand marshal Garithos is coming here with a platoon by his side.
Kael'Thas walks forward while Alexis and the Lieutenants stand by her side seeing Garithos coming through here on his armoured horse and a large group of elite soldiers with gray armour, all of them were elites. Garithos would stop and gets off his horse, walking over to Kael holding his large axe and his shield.
"Report Kael'Thas why haven't you attack the undead?"
"We have already taken control of the area, we drive them back and are holding position for my people to recover an –"
"You should have attacked the Undead by now Kael'Thas! Signal your armies to push forward, destroy them before they advance with a larger horde."
"Milord that is what they want us to do, if i send my elves out there we will likely run into an ambu –"
"You have your orders Kael! I trust you elves are clever enough to walk around it; right now the undead are preparing an attack on Dalaran so i trust you are clever enough to defeat their leader in charge of this attack here. Do not fail me again Kael you will press forward and you will destroy the undead."
"I... understand lord Garithos."
"Good now the undead will not attack Dalaran anytime soon so i will watch your progress from here on in, i will be leading the campaign here so i will give you an order to send your troops to the west."
Kael slightly nods to him and turns back and walks over to the group, he remains silent for the moment while Alexis walks in front of him. "Were going to press the attack; i will lead the first wave through the west to draw out the undead, you Alexis will lead the rest as the second wave."
"I don't like this plan Kael... allow me to take the first wave, if they see you they will –"
"Is there a problem here Kael'Thas?" Garithos said looking over to them
"No milord..." he looks back to him then back to Alexis and whispers something "No matter what happens... you take your orders from me... not him." He walks past her and heads outside while Alexis and the others stay where they are for now.
Kael takes a group of a hundred infantry to march to the west while the rest of the elves stays with Alexis who stays behind and wait for the signal, they do march forward but will be force to halt at a position and let Kael move through the undead territory noticing they have retreated further within. Garithos and his troops follow Alexis through the passage, staying away from their force and would just watch this.
Kael marches down the past with his troops, he takes the lead and would continue moving but stays at the ready and so do his elves knowing the dead are near, looking through the trees knowing they are out there, in a few minutes later Kael could have sworn he heard something, he signals them to hold position and stay at the ready, archers stands in the middle ready to fire waiting for the signal and Alexis can see them from a far noticing them holding positions, preparing to advance soon.
In the shadows there lies the Dark Ranger hiding with the undead looking over to the group, she slowly takes out an arrow and holds her bow in front of her to take aim towards Kael while he stands there, she looks at him for the moment as he looks where she is but couldn't see her but she did hesitated to release her arrow. Suddenly before she is able to fire the undead would press the attack, she looks to the side of the elves noticing a large group of undead infantry coming up behind them, they turn around and raise their shields, the archers take fire taking them out before they clash against them, Kael looks front seeing more of the undead coming towards him, his hands lights in flames and aims to the ground to send a short flaming wave to the ground and burning through the undead, taking a few steps back while his elves charges forward clashing against the dead striking through them.
The dead comes from the sides that hidden themselves in the forest, clashing against the blood elves on all sides but he soon would fire off a fireball into the sky signalling Alexis that they are under attack, she signals her forces and quickly make haste to join Kael before they are all dead. The Blood Elves were holding them back, striking through the dead so quickly while Sylvanas watches this, seeing Kael putting up a fight with his magic blasting the undead in front of him in flames and soon a large abomination appears to the side he would move his hands together to make a bigger fireball and aims to the face, he throws it towards the creature and it would just eat the fireball but a few seconds later the head and the chest would explode to pieces sending chunks of the body flying in other directions to the ground and cause some people to be covered in that blood.
Kael signals his troops to retreat once they have removed the dead behind them, they run back and finally Alexis would signal her archers to rain fire past the elves taking out the undead, Kael looks forward and helps those who are running, using one more magic up his sleeves to cause a symbol in the sky and making flaming meteors fall from the sky, sending them down to the undead and destroying hundreds of them when they continue to charge towards him.
"We charge for Quel'Thalas!" Alexis yells out to the elves and they all form together and charges towards the undead while Kael stands where he is still sending meteors down but would soon have to stop and let Alexis deal with this letting her striking through the undead with two swords drawn slashing them to bits along with the rest of the elves as victory was drawing near to them.
Victory was close to their grasp but the undead was not done yet because the death knight stands over the hill with another horde of undead archers standing by, looking down at Kael as he continues pushing the undead back, Kael would look up noticing a Death Knight but found out it was a female who is a blood elf, knowing who she is. She looks down at them and looks at the archers she signals the archers to fire down at them.
The elves who pressed forward got in their range and was taken down quickly while they attack, killing a few of them while the rest quickly raise their shields to block their attacks and the rest hold position and pulled back a bit to get out of their range. Alexis would run over to Kael looking back as more undead are forming together to charge "We can't keep holding them off Kael. If we can't stop those archers then we will lose the fight here."
"I will handle them... right now that Death Knight is a problem..." he looks back over to her "That's Alicia..."
"I thought she survived the war." She looks back seeing a ghoul coming towards her, she throws a knife and takes it out to the head "I can't believe they got her."
"I will hold the undead at bay; you go and take her out before she does something worse." He started to move back and looks over to his army "Fall back now! retreat for now!"
With the elves retreating Garithos would notice this and started to get crossed, although he was always like this but while Kael and his troops retreat the undead press forward while Alexis moves into the shadows through the forest, she goes past some of the undead who runs past her and moving closer towards Alicia but notices they have a few meat wagons ready to send a plague to the army to make things even worse.
Kael looks back seeing the undead coming "Damn these monsters." He raises his hand sending another fiery explosion taking out twenty undead and holding them for the moment.
Alicia looks back to her undead archers "Pull back and release the meat wagons –" She looks over seeing Alexis coming out of the shadows "Alexis..." she was about to draw her sword but Alexis swings her sword cutting the head off the horse causing her to fall back on the floor with the horse on top of her.
Alexis draws her dagger and stands ready looking at the undead "This is for Quel'Thalas." She charges and strikes through some of the undead while Alicia tries to get up off the floor
Alexis moved her swords back and they started to light in flames of the phoenix, she swings forward making an X in the air cutting through the undead and taking out one of the meat wagons that was nearby, she turns her attention to Alicia but once she turns towards her she was force to quickly block her swing from her sword then she kicks her to the chest sending her falling down the cliff.
Alicia looks back to the others "Fire the meat wagons!"
"But milady... were out of range..."
She sighs and looks over noticing Alexis is gone, she looks over to the blood elves seeing them destroying the undead quickly. "Damn them... she was only trying to delay our attack. We fire now then they won't press forward and they will not be any casualties." She looks back "Pull the army back to the undead bastion lets see if they are good enough to siege that."
Once she retreated out of there the undead who was by her side retreated while the rest that was fighting the elves were being slaughtered quickly due to Kael and his powers, Kael and his men press forward but they stop for now due to the meat wagons fired anyway, making a toxic clouds in front of them to hold them for now. Alexis would return back to Kael's side placing her weapons away and notices the rest of the dead are retreating.
"I guess we won't be chasing after the undead now, i hate this plague." she looks back to Kael "What are your orders now?"
"Hold position." He looks back to his elves "Fall back, those who still have the strength to fight then come with me and Alexis." He looks back to her "We need to see something before we meet Garithos.
"I know what you're talking about." She nods to him and Kael would go off the path and leading through the forest along with eight blood elves by his side and hers, going after the undead to see where they will go while the rest of the elves return to recover.
"What the hell is that blasted prince doing now!" Garithos said noticing the elves returning back but not Kael and Alexis "What are they doing..."
The Death Knight walks towards a large undead bastion that lies at the edge of the coast, the undead she brings with her returns inside and the necromancers and acolytes are already busy making more undead minions, obtaining more dead corpses to resurrect and join the attack once again, inside a Dreadlord who was green would be waiting for Alicia to return to hear the report on whats going on in the east.
Kael and Alexis would stand on the high ground seeing this large place, this undead bastion was well fortified and if they attack now they will sustain heavy casualties from this in fact they might not even be able to destroy the place if they have to fight that Dreadlord and the Death Knight, he has even brought demons by his side so this will be difficult without Garithos' assistance.
"Just as i thought... there bringing back another army to attack us again..."
"If we attack now then we might stand a chance but we will sustain heavy casualties if we underestimate them." She looks to Kael "Prince Kael... we cannot go down there this is too risky we can't win against that."
"That Dreadlord could pose a problem to us especially the demons; we could defend the beach again but... Alexis..." he looks back to her "Take these people and flee."
"What?"
Kael walks back down "Garithos... i bet he will order us to attack that place with all we got. We could destroy that bastion but i do not want to lose all of my elves in this matter."
"But why do you want us to leave the fight?" She looks back and walks down with him
"Because i need your help... and only you can do this for our people..." he looks back to her "I know you can do this."
She was bit of a shocked to know he would rely on her to do the job where he cannot do. She slowly nods and Kael would explain to her the situation, after that he took his leave returning back to the alliance alone while Alexis would take her leave with the rest of the elves Kael brought with them, heading to the north then go around to the east to return to Dalaran but they stay around the area to see the outcome to this.
Garithos stood there looking over to Kael while most of his elves return to the ruins; the others would set up defensive points around the area. "About time you have returned Kael'Thas, where are the rest of your people?"
"There is an Undead fortress on the coast, there preparing for another attack so i thought we can –"
"You thought you can show the undead how strong we are by running back here? Damn you Kael, now they will attack again. I want you to take all your troops and siege that fortress before we –"
"I don't have the siege types to destroy that place without your help, i will be walking into a slaughter house, i need –"
"NO. You will obey my orders and attack that fortress now; you serve me and so do your elves so you will obey me and attack the undead!"
"I cannot siege that fortress!"
He remains silent for the moment then looks over seeing the elves turning their heads towards Garithos and so does his men nearby. He looks back to Kael "DON'T talk back to me Kael... i was the one who helped you come to Dalaran, I was the one who brought you back to the Alliance even though your city is destroyed."
"You have been trying to destroy us elves ever since we got here, you're using us be pawns in your arsenal and i have had enough using me and my people to do your dirty work. Do it yourself!"
"Sergeant!" He turns his head towards one of his men "Escort the prince... back to Dalaran at once!" He looks back to Kael "Now you will come back with me or i will order my men to attack you elves."
Kael remains silent and the soldier would grab his arm, he backs off to get his hand off of him, he looks back to Garithos but doesn't say anything. He walks with the soldier back to the ruins and Garithos looks at the elves seeing they were in shock but Kael would not want them in this mess. Garithos would return with Kael out of there. Alexis saw the outcome of this and started to leave with the others knowing they would have to rescue Kael from Garithos, if this happens then it won't be long before the rest of the blood elves rebel and challenge the humans from this treachery.
"I will get you back Prince Kael'Thas." She said to herself "I promise."
