Diaval 

He/Him - 7ft - Fit

Diaval works in the selling of illegal gold fleck. He definitely gets the fleck from unwilling grems. Diaval is not a good dude. 
He works very closely with the mob boss Paris. 

He is tall and intimidating, he keeps his horns sharpened and shined. 

He spends a lot of time watching the grem fights. He's just a shady guy.
