Isaac

Mate: Adira

A cunning dragon that one day simply joined the lair on a whim and set up shop taming familiars and training young dragons in the Coliseum. Nobody really questioned it, nor did they go against it, considering he has a very off air to him- one that's dark and a little unstable. He claims to come from the deepest recesses of the plague biome, and has likely partaken in some twisted activities to get where he is.
He is, however, deeply devoted and loyal to those he becomes close to- though truthfully is very untrusting and doesn't connect easily. He's knowledgeable on battle mechanics and ruthless on the field; though this nobody really was surprised by, considering he's curt and a little scathing even in personable conversation.
The only individual able to keep him relatively humane is Adira, whom he once took in and trained, and the two are nigh inseparable. Nobody knows what they get up to in their dark corner of the den, but they both sit and watch everyone else and makes most they come across uncomfortable.
