Polyterons are strange elusive spirits only found in the Deep Umbra, anchored to objects that occupy four or more dimensions within space. On Earth, any such object is nothing more than mathematical theory, but far within the Deep Umbra, the laws of reality on Earth do not apply. Such objects not only exist, but the spirits attached to them thrive and grow strong.

Polyterons keep themselves to the Deep Umbra as much as possible. They serve the Celestines and Incarnae found there, and rarely have reason to leave the realm.

Every once in a while, one of the spirits will travel to the Astral Umbra on an errand for a Celestine, or to converse with the mathematical concepts found there. Beyond the Astral, Polyterons do not cross the Membrane as it forces them to conform to Earth’s reality. Despite the mathemat­ ical theories that describe such objects, the spirits cannot remain in their true form in the Middle Umbra or physical realm. The rigid laws of nature attempt to mold the extra dimensions into finite shapes, instead of the more fluid suggestions of the Deep Umbra.

Polyterons can be dangerous spirits to deal with. The spirits exist in time and space differently than Garou, and find the werewolves interesting. They do not take kindly to intruders in their homeland, and will capture a Garou for study if one stumbles into their realm. The dimensions of the spirit make fighting them difficult. Though Garou claws and teeth can rip the flesh of the spirit in the Umbra, they cannot damage all parts of the spirit, making it resistant to attacks. The attacks of the Polyterons are similarly different, as they do not claw at the flesh of a Garou, but instead the time of one, cutting away bits of his future and past as they strike. A Garou killed in this way simply falls to dust as his life force meets with timelessness and ceases to exist.
