Homebrew Darkness Elemental Species Details

A being from the plane of darkness. You have somehow found yourself on the material plane for longer than you anticipated and have gained sentience beyond that of your fellow kin. Perhaps you found yourself in the service to a wizard who released you after he realized you couldn't do as he wanted. Maybe a sorcerer's spell went awry and you found yourself free from the very moment you were summoned. Or maybe still, you forced your way through the planar barriers when they were thin. Either way, you have lived in the material realm long enough to adopt the semblance of your mortal companions.
