Bone Jesters (also known as Mors) are a type of undead Gigant, amongst the smaller and weaker breeds. They ressemble snakes or worms made of segmented bone plates. At the top sit a feral, albeit vaguely human-looking skull. These creatures decapitate their preys, replacing their heads and spines. The body is then kept alive via special chemicals they produce.

They are created when multiple Gigantes die in a single locale. Their collective urge to continue predating mingles with their spilt gore and Ambrosia, and infuses into one corpse.
