Currently in development as the setting for an independent pen & paper role-playing game, "Mortasheen" is a world I've been populating with my own original monsters since almost as far back as 2003; an impossibly vast, biomechanical city at the apex of a toxic, irradiated world, Mortasheen is populated by mad geniuses and otherworldly mutants whose daily lives revolve around the bio-engineered monsters they modify and train. It's lawless, polluted and impossibly dangerous, but it's a world that also exists in surprising harmony. Its average citizen may be an aggressively bloodthirsty, venomous parasite, but that doesn't mean they're bad.
Below is a link to every monster in Mortasheen's current canon, illustrated by myself. Dating back over a decade, the art and writing quality as well as the level of taste may vary wildly; new monsters are currently added almost every month, while older monsters are selectively rewritten and sometimes redesigned. It's a never-ending project!
Patrons pledging just a buck a month can see in-progress concepts, offer feedback on future monsters, view secret sketches, get early sneak peeks at RPG content, and help me put food in my organs!
NEW! Browse monsters in order of the latest added, all the way back to 2011!
