A Diversity of Zobani

Zobani are like the small things of the spirit world, like the spirits of combs or viruses or other such things. Most of them aren't even bound to object manifestations or forms and are generally free-floating in the morass of the Near Realm. Zobani are the things that crawl inside creatures and people and are responsible for a lot of supernatural type creatures, changing things in much the same way bugs make galls in trees or those nasty Saccula barnacles mutate crabs. They actually create complex ecosystems in the "shoreline" between the real world and the spirit world - some people can even see them, even though these people often go mad. Those that don't are often trained as alchemists, a sort of metaphysical physician who specializes in getting those nasty cases of parasitism taken care of.

Balak are a step up, and some of those take recognizable forms, even humanoid ones in some cases. Mobs are a step down, and are like deep-sea detritus that other spirits feed on.
