Everything

Most of the dangerous spirits the Garou fight in the Umbra are Jagglings. Nearly all of them can be considered part of the Weaver, Wyrm, or Wyld — in fact, some are fanatically devoted because they’re formed from a portion of their patron or master. Pattern Spiders, Nexus Crawlers, Banes, and Englings are all common examples. Most loyally serve an Incarna, though a few serve Celestines directly. Some develop (or earn) free will and independence from the patron, although this is more common on the remote fringes and smaller realms of the spirit world. Werewolves are intimately familiar with the Jagglings who teach them Gifts, including a wide variety of animal spirits who demonstrate the instincts and intellects of creatures in the physical world, albeit in very idealized ways. A Jaggling may also serve as a reservoir of spiritual power, as is shown by Englings capable of providing Gnosis to an entire pack (or even a sept) of Garou.
