Gil was never one destined for greatness, or so he alway thought. He never stood up from beign something big, it didn't suit him. It was not long after he discovered he was dragonborn that is.
Gil was an orphan, his parents died when he was 8, a disease that struck the village he lived at. He followed villagers that went and moved to the main kingdom. He was since then a survivor, he had to survive the wilderness and after that survive the city, more than once he was close to starving but he refused to give up. He searched for food in trashcans and set up his own traps in the wilderness.
He learned trough books he read in the local libraries berries that were safe for eating and better ways for surviving in the wilderness. He learned to pickpocket and to lock-pick trough practice and even learned to fight with a wooden sword. He was always a fast learner and not long after he learned how to use a bow he became a great huntsman. He loved the thrill of the hunt and always went to hunt, but he felt that hunting wasn't for him. The went to cooking, and logging, and fighting, and so on.
His whole goal in his early life was to learn something that he could live from and he enjoyed. He became adept in many forms of fighting and magic casting, he learned the components of alchemy and enchanting, for a few years he settled up a shop and a smithy. The last he went for as he ran out of options was an adventurer, as he was never one for adventure, but destiny said otherwise for him. He loved it, the thrill of going in a ruin and not knowing what danger could befall him, or going up against some crazy strong foe and getting out victorious only a few hits from beign defeated. He never left any of his other skills go to waste, and always used them, and they were always useful in his traveling.
His traveling lead him to Skyrim, it wasn't in the best of ways, he got one hell of a welcome party. It was his luck that he decided to cross the border when Ulfric Stormcloack decided to appear. He got caught.
Of course destiny wasn't gonna let him die in a execution in the middle of nowhere. So a dragon appeared, after a long time that one wasn't seen. We all know how that ended. And so his adventure started, by the end of his adventure and after he finally killed Alduin he was 19 and the best warrior of the providence, his skills in all fields have gotten better, including his more...despicable ones, such as pickpocketing and lock-picking. Desperate times call for desperate measures, he told himself.
Gil was always a kind soul, always putting himself in front of others, always helping those that seek help, no matter who or what they are, Serana was the biggest example of this. Speaking of the vampire, she was one of Steksall's biggest friends. They clicked form the beginning, they say master minds think the same, and they always thought the same. Even if one was a Vampire hunter and one was a Vampire herself it didn't stop the two to become friends.
What poor Gil didn't knew is that Serana had a major crush in the dragonborn, this started to happen a little after the whole incident of vampires wanting to conquer the whole world and stuff. Even before that, Serana felt attracted to the Nord. She knew that she was a lot older than him, she didn't knew exactly how much due to her beign sealed away, but she was sure at least a 50 years due to the change in political powers. (Do tell me if i'm wrong) but that didn't stop her form crushing on him, she wasn't a teenager and she wasn't going to beat around the bush about it, but she decided to wait. Steksall had the soul of a dragon, and that affected more areas than just his power, it looked like the age at which his Hormones are released is more around 20 years, and because of that he didn't showed a lot of interest in woman in his adventure. She choose to wait as making a move while his Hormones were still sleeping would make the whole thing just awkward.
Thanks to his Hormones sleeping and his childish mentality of protecting everyone he can, it was like having a child in the body of an adult. A crazy strong adult that was not only a seasoned veteran but an expert in more than one field of magic. If you were to ask anyone, they would tell you that is one of Gil's biggest factors to all he accomplished. Most females that knew Gil respected him, if not had a little crush of their own, but like Serana knew he didn't had an interest on woman yet, and 'protected' him form, in their own words 'Whores who want to tint his Innocence' As he hadn't had the 'talk' yet, you know, dead parents and all that.
After the Alduin incident things were pretty calm in Skyrim, and Gil liked it when it was calm, he could explore all he wanted and not worry about some maniac dragonborn who wanted to kill him, or some crazy dragon who wanted to eat Nirn. He just could do anything he wanted. He was wearing the Nightingale Armor, he was always a fan of beign fast, and better yet, it was very appealing to the eye, it looked cool in more modern words.
Gil was walking down a dirt path, hearing nature at it's best. Unlike most Skyrim, this path he was walking on was actually green, and not pale white like most places even remotely close to the edges of the land. He was just walking, thinking of what to do today, as he did so he found a cave in the side of the road, and his adventurer instinct ignited within him. He got his torch and his Steel sword, why steel? He enjoyed the feeling of a fight, and he had some pretty powerful weapons, but the feeling of the fight vanquished if he 1-shots the enemy. Back to the cave he explored it, and the further he went in, the weirder it got. He walked down the cave for a few minutes and looked back, the light form the exit wasn't visible any more, and he couldn't see any walls. 'No going back now' He thought as he kept walking,
Soon, he found the other side of the cave, but he found what he didn't expect to see. Unlike the light forest he was walking at before, this was a deep forest, the part that he was in it looked like leaves almost covered the sun. The trees weren't that tall, but there were just too many trees. He looked back at the cave, he learned trough experience that things this peculiar usually were a one-way street and he could not back up now, He was right as the cave behind him was now sealed with stone, he knocked on it to see if it was hollow, but the sound it made was that of a solid wall. He sighed and looked around him.
The first thing he noticed was that temperature was different from before, and if it wasn't clear from the whole cave now a solid wall stunt, this was the result of alteration magic, a wormhole if you will. The second was that the species of trees were some that he din't knew. The third and final was that he was surrounded by werewolves. He just took out his silver blade and put a temporal fire enchantment on it. He then with his free hand charged up a chain lightning and fired it, expecting it to weaken the beasts before the real fight started, but he didn't expect for the werewolves to fall to the ground twitching.
Werewolves were a force to be reckoned with, with their primal instinct and rare not fear of death, these nature berserkers can take a lot of punishment. Even some new Werewolves can take on a few competent warriors, and the gap between a new werewolf and an alpha was huge, so much more when there were multiple werewolves. For them to all fall with one chain lightning was very odd. He checked the corpses and found they were like werewolves but must be some monsters native to the area, as they had some bone-like armor. He didn't knew any werewolves that were like this back in Skyrim.
He then whispered Laas Yah Nir, Life, Seek, Hunt, aura whisper. He detected that other creatures were heading his way, most likely due to the shouts of pain from the not-werewolves. He readied his weapon again, this time he would see how strong they were face-to-face. He encountered some werebear creature, but decided to call the not-werebear. At least they shared the same fearless attitude as he pierced one where the heart would be and another one jumped at him without hesitation. He slashed it as he sidestepped out of the strike and parried another attack form another beast. 'The best kind of blow is the one that misses, the second one is the one you block' he recalled form one of the book he read. He pierced again and took some distance between the beasts and him. This weapon wouldn't do. He putted it back to the other dimension we call inventory and took out a rapier, a weapon form another land. Fast and deadly, made for piercing attacks, perfect for the fur and looked cool, another point in his books.
He rushed off to battle again and found it much easier to pierce and kill. Attack, evade, parry, block, kill. This repeated for a couple of hours and it looked like they wouldn't stop coming, He resorted to his stamina as he fought. He loved this feeling, the feeling of fighting a thousand foes and raising your sword in the middle of a corpse full battlefield, but after a while it just kind of got boring. He finally got sick of it and started firing chain lightning at everything that moved. His reserves were pretty darn big and refilled pretty fast too. It looked like there was a smaller amount of magika in the air, so his reserves took longer to fill, but it was there. A lot of things came his way, not-werewolves, not-werebears, boars a few birds, giant snakes and scorpions, a bit of everything.
What was the most curious to him was that a few minutes after death they dissolved into nothingness. After he electrified the last one, he used aura whisper again and found nothing else going his way, but did notice that there were more humans nearby, some had a different kind of feel to the aura they gave, another race he presumed. He decided to rest a little bit and just climbed a tree and sat on a branch, getting comfortable to start thinking on how to go back.
MEANWHILE- Beacon, Ozpin's office
Ozpin was watching with Glynda the whole fight the mysterious hooded man had with countless Grimm. He first used a lightning on some beowolves and fell dead, the two presumed it was his semblance, and after a few hours of watching him kill Grimm like it was child's play, he then started shooting the same lightning form before to zap 10-15 Grimm at a time. They then noticed it was not his Semblance, but something else. After the fight we checked the Grimm population in the emerald forest and Glynda was shocked to see he killed off 60 percent of the Grimm on the forest by himself. They didn't knew why or how so many Grimm even appeared at the same place at the same time, but they didn't knew it was only Gil's rotten luck.
Ozpin took a sip from his coffee and looked at the image of the hooded figure taking a break from the previous fight.
"Interesting" He said as he looked at him and at the new students from this year. They were wary as the fight could be heard from kilometers away.
