Nuro

Nuro is a dragon who often walks alone, and perhaps it's for the best. Violence and savagery are the only things he's known and he be replicates with greet glee in those actions, with little mercy for those under his claws. He's feral, never really having had a proper clan or group to learn from, on how to act with others or think with intelligence. He's a survivor yes, but through force and not thought. Nuro follows on his primal instinct to continue to live, he's never been and never will be exceptionally clever.
In terms of social interactions, Nuro isn't greatest. He lacks any form of respect for others, and he has a difficult time following others emotions as well as even his own.
Nuro is extremely stubborn, once he's set you'll never move him until he's dead. He doesn't stop and won't stop until his very last ounce of breath.
However, he's not a stone serious creature, he's oddly cheery, which might make him even worse in some eyes. He enjoys what he does, and he does hold a sense of humour, thought very dark, twisted and strange.
Once Nuro comes to like something, whether he knows quite why or not, he becomes fiercely protective of it. It his now, at least in his mind and he will defend it from the slightest of threats to the most dangerous that would probably kill him. He does not care, it's his.
