The Lord of the Deep
The Lord of the Deep is a fungoid distributed intelligence that dwells in the Middle Deeps of Venarik’s Deep. It has a symbiotic relationship with a tribe of gnomes: it colonizes them, establishing a mental link, and acts as their protector. When the gnomes get very old it sends them out to be eaten by the local monsters (trolls etc.) and then it infests those monsters, providing it with expendable warriors.
Those colonized by the fungus grow a kind of grey fuzz that resembles short hair.
