Might of Dragonblight.
"It's done," Alexstrasza said as she, Thrall and Gromm landed at the Temple of Storms, the sound of marching armies echoing below them. "We have the major forces of Northrend gathering on all sides of Dragonblight, and an army of Titan constructs that cannot be used against us now."
"So what's the plan?" Sylvanas asked, as the heroes gathered in front of Thorim's throne.
"Simple, we assault Naxxramas head on, and that will signal the united armies of Northrend to attack on all sides," Alexstrasza stated.
"I might have a solution for bringing that thing down," Kalecgos piped up. "I'm going to return to the Nexus, but I'll keep one of the dwarf's communicators to signal when my plan is ready."
"Are you going to tell us this plan?" Ysera asked.
"Now dear aunt, where would be the suspense in that?" Kalecgos smiled, before diving off the edge of the temple.
"So, Kalecgos has a plan for bringing it down, Sylvanas will lead the strike into Naxxramas, destroying whatever horrors the Lich has amassed, and then stop him from opening the doors for the Legion." Alexstrasza stated.
"What about you my queen?" Sylvanas asked, suddenly feeling the weight of her armour increasing with the responsibility.
"We will fight outside, destroy the ground forces, ensure the Nerubians cannot rise again for another hundred thousand years," Nozdormu stated, his appearance surprising everyone.
"And we must stop them from raising Galakrond; we must destroy it before it gains the same strength he once had." Alexstrasza stated.
"We need to focus on the big picture," Alleria stated, slamming her fist against Thorim's throne. "The Lich, Galakrond, they mean nothing if we let the Skull of Gul'dan leave this continent. Unless it is in our hands."
"No," Medivh stated, as he appeared in the group. "To ensure the Legion are not given an open door into our world, the skull must be destroyed, along with any other artefacts of equal power."
"Does that include you?" Alleria snarled, her hand moving for a dagger. "You're an artefact of equal power."
"We'll see," Medivh stated. "Good luck with your 'war', I will be awaiting you when you're ready for the real battle."

The Lich felt a shift in the wind standing atop the floating fortress of Naxxramas, as he looked over the near infinite army he now had at his disposal. Garona had fallen quiet, and the Lich presumed she was dead, but she mattered little in the long run. He heard a familiar roar, and turned to look north, seeing several dots against the skyline.
"Dragon Queen! Have you come to die with your kin?" The Lich's voice bellowed over the icy winds, which seemed to be shifting constantly.
"I've come to save them from your vile magic!" Alexstrasza roared back. "We've come to end your short reign!"
"You are weak, you have no army, and my reign has only just begun!" The Lich laughed.
"You are right Ner'zhul!" Alexstrasza roared, she and the others hovered at the edge of Dragonblight. "We have no one army to aid us; we have many!"
Suddenly the Aspects roared in unison, and the Lich was caught off-guard by war-horns sounding on four sides. He glanced west and saw the Taunka, Tuskarr and other natives of the western reaches of Northrend pouring across the narrow bridge connecting Dragonblight and the Borean Tundra. To the north-west and south-east, Vrykul soared into the wastes on their proto-drakes; with more warriors charging into Dragonblight on foot, savage wolves at their heels. To the east and north-east came Storm and Ice Giants, and at their feet Drakkari Trolls, flooding down the steps of Zul'Drak.
"Pitiful!" The Lich laughed. "These 'armies' will fall, and rise again at my command! You have brought fodder!"
Alexstrasza simply incinerated the Nerubian defences along the northern edge of Dragonblight, before a mass of black swarmed in from the Crystalsong Forest.
"We defeated Yogg Saron, and awakened the army beneath Ulduar," Ysera roared. "Titan constructs may fall, but they will never serve you!"
"No, but I know what will," The Lich replied, pointing Frostmourne at the ground between Naxxramas and the Dragon Queen.
With but a thought, unholy lightning shot from the blade, hitting the largest dragon skeleton that littered the wastes, and the Lich could feel the unnatural life being kindled in the corpse beneath him. When he felt the cost of his resurrection beginning to take its toll on him, he stopped channelling his power, and quickly teleported inside Naxxramas.
"Attack!" Alleria roared, and with that they soared forth; seeing the Dragon Wastes beging to crumble and crack.
"Burn the bones!" Alexstrasza said frantically.
"Onyxia, get us to Naxxramas, then help Alexstrasza deal with that thing!" Sylvanas whispered, as the other heroes leapt on to the Obsidian dragon's back.
Onyxia accelerated toward the floating citadel, while Alexstrasza, Ysera, Ysondre and Nozdormu attempted to incinerate the bones that slowly emerged from the ground. Sylvanas glanced down in time to see the largest dragon skull she'd ever seen stir, whitish-blue balls of light filling the empty sockets; unholy eyes that seemed to stare at her.
"Come then 'heroes'! Test your might against mine!" The Lich's voice echoed across the wastes, becoming almost deafening as the heroes drew closer to the necropolis. "Frostmourne hungers!"

For centuries the wastes of Dragonblight had been quiet, peaceful, and without much incident for the Dragon Queen. But ever since her kin melted Icecrown Glacier to the north-west, the region had been turned into one of turmoil and chaos. In their battle against Deathwing the shrines had been destroyed, and centuries of ice had been melted in seconds; now the land where thousands of her kin came to die, was covered in warring peoples.
Alexstrasza circled low over the remains of the Wyrmrest Temple, followed by Onyxia after she had dropped the heroes on top of Naxxramas. As Alexstrasza incinerated the hordes of Nerubians that scuttled over the rubble, Onyxia used her power over the earth to shift the rubble, and let over a hundred dragonkin fly out of the Sanctums.
"We may defeat the armies of the dead, and the hordes of Nerubians, but against Galakrond we may be doomed." Alexstrasza roared, as she and Onyxia returned to breathe fire on the large dragon skeleton that was forming north of the Wyrmrest Temple's remains. "It took so much to defeat it when it was alive, in undeath it may be even stronger."
As the skeletal form of Galakrond began to stand, the ground at its feet swallowed its claws, enraging the unholy creature.
"Do you think that if the Lich is defeated, this abomination will die?" Onyxia asked, staying close to Alexstrasza, as the rest of Galakrond formed below.
"I do not know, but we must try to defeat it any way we can," she replied, swooping low to attack, but pulled up sharply when Galakrond tried to bite her. "I see its taste for its own kind remains."
Galakrond was almost complete; Onyxia was using her power over the earth to keep its claws buried, but the rest was essentially fully formed. The armies on all sides were keeping their distance from the gigantic proto-dragon skeleton, including the undead and Nerubians; when it bellowed a chilling, echoing roar, everything fell quiet.
"Spirits protect us," Ysera said quietly, but in the silence following Galakrond's roar, Alexstrasza heard it.
"It may not bleed, but we can kill it!" Ymiron bellowed, soaring past the Dragon Queen.
"Heroes hurry!" Alexstrasza prayed quietly, as she saw the Proto-drake mounted Vrykul joining the fight against Galakrond. "We may need your help."
