Potestas is a lean red dog with green eyes. Generally easy going.
Now has white makings on his body and ears.
P.S. his ears are very sensitive.
Basically, Potestas is a guy who considers himself deep without being a douchebag about it. He's the kind a guy who likes to go to inner city diners in the rain and sit near the window. But he wouldn't say that. He's the kind of guy who plays a few things on the guitar before bed, but you'd never hear him admit it. He's the guy who has a computer full of little stories and half-written things that he denies the existence of. That's the kinda guy he is. He's playful, but there's two shades to him.
He fought in a long and terrible war. When he got back, his family was dead. He had never married or had a long term significant other, so he just sort of began traveling. He fingers still know the movements to steady his gun and find the target. His eyes still know how to search for movement in a field. His ears still atuned to the fine sounds of jungle and gunfire. He's still a soldier.
---update---
Potestas now wears a military surplus jacket and dog tags along with a pair of faded jeans. He has a scar on his side and on his cheek bone from shrapnel. Has grown his hair out to his eyes. Was originally regulation MARINE crew cut. Has a tattoo on his chest of his dog tags.
