Steve is a friendly Gnoll who lives near Yangahr but grew up in a camp that grew melons. Hence the name. He has a wife named Cheryl Meloncamp who is...around somewhere? Steve is the gosh darn nicest guy you will ever meet.
In an alternate timeline (Tabletop Day 2015 Live Stream Evil campaign), Steve's home of Meloncamp was attacked and his wife Cheryl was killed. This caused Steve to turn evil, adopt the Christian name Evil Stevil, and gain a love of rumbling.
Steve is played by Mike Bachmann
