Skeletons were undead animated corpses similar to zombies, but completely devoid of flesh and did not feed on the living. They ccould be made from virtually any solid creature, and as such their size and power varied widely. In addition to the basic humanoid skeleton, there were also skeletons created from wolves, trolls, ettins and even giants.
The undead form of skeletons was held by necromantic energy, which kept otherwise loose bones and joints together and conferred on the undead corpse a glimmer of vitality and rudimentary intellectual capabilities.
