Demir: average height, black hair, black eyes, lithe build, wears all black (and a little red), carries two small daggers (and knows how to use them)
Demir is a man full of secrets. His biggest one: he's a werecat. (Don't tell him I told you!) He didn't know his parents, but was raised by a mix of cats and humans on the streets of the capitol city, and he's never really left. The city is like his own little realm: he knows of everything that happens, both legal and illegal. Often, he's the one making it happen- on both ends

He runs a kind of underground network- and by that I mean he and his "agents" literally use the underground passages in the city that no one else knows of. He isn't close to anyone, at least not enough to tell anyone his secret. He never gets flustered but is excellent at thinking on the spot and deflecting questions. Most would say he has a sketchy moral compass, but he has a few very strong convictions and sees himself as a kind of guardian of the city. He puts himself on the line for others very often.
He's cat-like in many ways. He despises rain, loves warmth, acts very aloof/condescending, extremely sarcastic and flirty at the same time, is a control freak, and loves driving other people out of their minds (especially my main character...)
