Malus is your typical good time bard, he likes playing music on his lute and drum, pretty people, and traveling around from place to place. Despite being born from a devil Malus is an extremely kind hearted man, whose willing to stick his neck out for anyone who might need help, even if those people might turn around and stab him in the back.
Malus is also unfortunately pretty dumb, being unable to read.(8 int on his character sheet) He does however have plenty of street smarts, having traveled around ever since he was a small child.
Overall Malus is just a good guy whos just trying to do his best
