So I don’t know about much of your characters, but generally what is Richards, personality and backstory?

Assuming you want the most used canon, here you go.

Richard was born as a wildtouched to two human parents. However, he didn't awaken to his alternate nature until his teenage years. After that, he went into school, trying to become an EMT or paramedic. Eventually he found out people were tracking him for his Wildtouched status, and went to ground. Following a few years of being on the run, he ended up on Kaerwyn. After adventures there, he decided to finish his medical degree and now is the EMT/Paramedic for the place.

Personality, he's rough around the edges but has a good heart. Likes metal music, plays guitar, freerunning, flying. He's recently admitted he's demisexual to himself.
