Onum
The dead and otherworldly. Those things which the To-Na-Onum hunt. It is not known for certain why the dead rise. Death of the living is known to be the leaving of the spirit. It is true this possession of the recently deceased was not always the way, and not every body returns undead, but enough do. Most of the Onum are not conscious, they are instinctual creatures who do not discern the difference in their prey. They do all they can to press on in spite of their constant inevitable decay.

Waking the Dead
The dead do not sleep in Ager Ethe, Oler Althe, or the greater of Cirrus Ethereal. Reanimation comes by many channels. As a Story Guide you may or may not want to include that all which passes away without proper rights spoken, without proper burials, comes awake in a new form. The inanimate flesh rarely retains the spirit of the passed. There is something coming from somewhere which is always waiting to get in. Onum do not rise in consecrated areas, but out beyond the reach of the To-Na-Onum, there is always the possibility of the recently deceased to be wandering in Onum.
