Corpse-candles

Undead spirits. Corpse Candles can create the illusion of being a whole, healthy creature by cloaking the hideous remains of its once-living body. They lurk in water and exudes a beckoning light that magically attracts victims. Those seeing the glow must resist a 7th level spell, with failure resulting in the victim falling into a deadly trance. (He then has 4 pts CO drained each round until death.)

Corpse Candles and Corpse Lanterns are lesser and greater manifestations of the same basic sort. They are remnants of those who, already lying unquiet, were flooded in their graves.
