Rust

Intro Monster, hunted humans and monsters for food, heavily injured, down an eye, grateful you saved him, protective of you despite being starving and injured. Can consume magic that you offer him. Normally done through a kiss. When you found him, he was comatose. It's how you brought him back from the brink. Extremely fast and strong for his size. You own a farm and found him half dead in a pile of mud. He can only digest meat or direct magic nutrients. Healing magic doesn't work on him. Gets cold.
