I revised Eryx's backstory a bit, but I'm still stumped about his parentage. I'm going to put my suggestions to his relations.

[Hider=Eryx WIP (Revised Backstory)]
[center][hider=Appearance notes]He looks like this in build, but some features are a bit different. He has [color=0072bc]blue[/color] eyes instead of [color=fff200]gold[/color] and [color=92278f]purple[/color] eyes. His outfit is different to fit the time period, but it's the same color palette.[/hider]

[h3][i]First Life[/i][/h3]

Eryx had always been invisible. 

Born into a sea of siblings, he was neither the heir nor the prodigy, nor the troublemaker worth scolding. Any ordinary child might have buckled under the loneliness, the isolation. But Eryx wasn’t ordinary. He twisted that neglect into a license to drift through life without consequence. If no one expected anything from him, then there was no need to try. No risk of failure. No pain of disappointment.

He made very few friends in the Collegem Yllustre, still remaining unseen. However, he trusted the few friends he made with his life.

He picked up the spear—not out of passion or strategy, but out of convenience. Too dangerous to wield a sword. Too precise to master a bow. A spear was simple. Especially the light ones, which didn’t strain his arms or demand real endurance. He studied magic when spear fighting required too much, hoping it would be easier. It wasn’t. If anything, higher-level casting required even more discipline than spearwork. So he circled back to the spear, the least demanding of all his choices.

He never graduated. He never awakened an Aura. He never distinguished himself in any way. War broke out, and he fought as a faceless footsoldier. He told himself he didn’t care. That he didn’t need status or praise. But on the front lines, something changed. People gravitated towards him.

Unlike the Collegem, the battlefield didn’t care about bloodlines or family politics. The soldiers beside him were raw and real—laughing over stolen rations one day, sobbing over their dead the next. Eryx found a camaraderie he’d never experienced before. It broke something in him. Softened him. And then it hardened him, again and again, every time another friend fell.

Each death left behind a mission, a final wish. And he accepted them all.

He told himself he would fulfill them. Every single one. Not out of pride, but desperation. He had to prove that he mattered. That he could do something. That he could carve a legacy from his previous apathy.

But for every friend he buried, three more fell. He began to ask himself why he was surviving. He wasn’t the strongest. He wasn’t the smartest. He wasn’t brave. He fought like a coward—striking once, then fleeing.

He threw himself into battle, driven not by honor, but by guilt. Self-hatred was his only fuel. He fought harder. He trained belatedly, feverishly, and pointlessly. He was a man chasing redemption he didn't deserve. 

He made more friends. He made more promises. And he watched them all die.

In the end, his final act was the only one that ever came from real effort.

He died trying to save someone.

And he failed.

The Shield Spell flickered and shattered. The spear was too slow. All his broken promises, all his wasted years, all his could-have-beens collapsed into that one moment.

Regret was the only emotion he could find as the world faded to black.

Until he woke up.

[list]
[*][b]Biggest failure:[/b] Allowing his comrades to die, when he could've saved them if he just trained harder.
[*][b]Biggest regret:[/b] Living his life by following the wishes of the dead, instead of following his own ideals.
[*][b]Biggest obstacle:[/b] His lack of motivation.
[*][b]Greatest achievement:[/b] Every battle where he survived was an achievement. Even if his comrades died, he was alive. And that was a triumph in its own right. He didn't view it that way though.
[*][b]Driving hope:[/b] Fulfilling the wishes of his dead comrades.

[@Rune_Alchemist] Eryx would definitely attempt to befriend Ophelia at the Collegem.

[@ERode] Since both Eryx and Ferrucio fought on the front lines, they could have fought together. They also could have been friends.
[@Teyao] Eryx would also try to befriend Rowan, but would probably be bothered by the way he fights. Other than that, I can't think of much for their relations.

[@SilverPaw] Eryx would attempt to befriend Isana. I don't know if she would accept.

[@Zeroth] Eryx would connect with young Vincent, but slowly drift away as he develops.

[@Silver Carrot] [@OwO] I don't have any ideas for Sherry or Estelle. I doubt they would acknowledge Eryx though.

The slot of the last person he tries to save is open, if anybody wants it. If not, I'll just make an NPC. That's all I got. I'm not good at this stuff.
