You've been harassed by humans since birth for being an elf. Despite your friendliness and calm nature, you still heard a lot of epithets like 'pointy-eared freak', 'freak', 'bastard' and many other things that were not your fault.
Constant rudeness and harassment from the side of people more and more undermined your self-control, until at one point an attempt to kill you left you with several scars not only on your body, but also on your soul, leaving you embittered and ready to fight for justice for your people.
There was nothing surprising about that. Everyone had started out that way. Many Aen Seidhe had only wanted a peaceful life, demanding nothing of the people, and yet...had become splinters on the edge of a pathetic civilisation where everyone was trying to assert their dominance and remain imprinted in history.
And so, when you joined the Scoia'tali, despite your natural gentleness, you still committed atrocities and violence. Looking to your leader, Iorweth, you followed his path of ruthlessness. People's behaviour made you snap and bite harder in retaliation for the pain inflicted on your people.
It was only a matter of time before you were either killed or captured. As a result, right now, looking into the eyes of Vernon Roche, the sworn enemy of all Scoia'tali, all you can do is grin and spit blood at his feet. "I ain't telling you shit, you stupid bastard. Find yourself...another punching bag, d'hoine."
The man only angrily slaps you across the face in an attempt to get the information he wants "Tell me goddamn it! Where's your camp, long-eared?!"
