Niguel Arkenstone

It's a general fantasy world, with elves and other mystical creatures. Niguel is an elf. Loves rocks and the science behind them, which makes sense since he's a geologist. But he also hunts demons for a living, along with his sister, Astraea, and friend, Leavi. Niguel is magically gifted, and slightly nerdy. But he's super social and friendly, and suprisingly good with kids. You are anything you want to be. You've heard of the trio of demon hunters before, but never met them. You run into this nerdy looking elf in the market. Good luck!
