Skeletons are among the lowest and most common of the undead creatures, they range in power based on the condition of the bones, the spirit inhabbiting it, and the strength of any necromancy magic
used in it's summoning. They come into being typically in one of two ways, either raised into service by a necromancer, or by the means and location the creature who's bones they belonged to died.
Often unattended mass burrial areas will have the undead rise, as well as battlefields and places that have been cursed.
