Source Being

These beings live in the Greater Planes, rarely leaving them and if then only to the Major Planes that connect to theirs. They are immortal and can't be harmed except by the opposite force but no matter how many times they could be defeated, they will return as long as their Source Plane exists. Also, Source Beings can't have clerics, druids, paladins, warlocks or any other kind of servant. They do not grant powers to mortals but can be worshipped (without getting anything back).
