Spirits are minions of the Nine created from their own essence to be eyes, mouths, hands and sometimes fists in the mortal plane. All the Nine use spirits but they don't all use spirits the same way. It is widely believed by theologians that while the Nineare truly mighty, their power is not infinite. It presumably takes a tiny portion of a deity's power to empower mortal spell casters or create spirit minions. It is noted that deities that have relatively large number of mortal spell casters usually have relatively few active spirits and deities that have relatively few mortal spell casters tend to have many of active spirits. Hallisan, Khemra, Phidas, and all have comparatively large priesthoods and comparatively few active spirit minions. Of these four, has the most but she seems to have sacrificed quality to gain quantity commanding very few spirits of great power. Greymoria, Maylar, Nami and Zarthus have relatively small priesthoods and relatively numerous active spirit minions. Like with many things, Korus lies between the extremes of his siblings with a modest number of spellcasters and a modest number of spirits.
