Khaayam came from overseas, and doesn't talk about his past or family at all, which Puya finds weird. Khaayam also has a weird accent, according to Puya. His character is a mysterious bat named Rua, who is almost never depicted with his eyes open.

Khaayam, a game designer on a silly adventure RPG game and creator of the shopkeeper of the game, Rua. 

 Rua - A shopkeeper who helps Puya with tips and items for his journey. He came from somewhere out in the galaxy, far from Puya's home, and his eyes look like a distant galaxy. His eyes are rarely open, so Puya always believed he was blind, which he isn't.
