Pictured here is a troblin guarding the Mountain Hexagon meatpacking warehouse. Fresh meat is rare in Goblinburg, and as such it is defended by the most resilient of troops.
Troblins are goblins with a fair amount of troll blood. Their regenerative ability makes them cheap to maintain and tough in a fight. Unless their opponent is aware of their tendency to pyrophobia.
It is rumoured that troblins were created by the fleshmakers. Which would make sense, since the produce sold in sinew shops comes from herds that are butchered over and over again.
