|Environment||Pit of Gormuz|
Source: Mythic Realms, pg(s). 29
It emerged from the Pit of Gormuz at an unknown point in history. However, unlike its greater brethren, it does not choose to range farther abroad. Instead it dwells in Offal Mountain within the Pit, leaving only when summoned.
A follower of Rovagug can summon the Crawling Hunger using planar ally. When summoned in such a way, it requires a gift of at least half a dozen sizable creatures to consume to secure its obedience. Alternatively, magical items that create food or remove the need to eat can be an acceptable sacrifice, though its inexhaustible hunger will overwhelm their magic and digest them within a few days. If the summoner does not provide such sacrifices, the Crawling Hunger will immediately consume them as a substitute.
