Deepwallow is a village built on a swamp located in Heretic's Horn, just south of New Sheoth.
Beelei owns the northernmost house, Erver Devani's is found to the south while Dulphumph gro-Urgash's to the east. Its three residents are all quite paranoid; Beelei and Erver Devani being scared of "them" and never leaving their houses and Dulphumph gro-Urgash warning people how dangerous scalons are.
It has two wharfs, one of which has a small wooden boat moored to it and another which is nearly completely destroyed by a growing spore tree. It also appears to have some sort of garden, although it is unattended and only contains a few Blister Pods and Fungus Stalks as well as a couple of broken barrels.
