Dhinnilith

Dhinnilith was a phantom city rumored to appear on moonless nights every few years, hovering over the waters of the Vilhon Reach, just north of the Chondalwood.

History
Dhinnilith was originally created in -1603 DR by noble families of Jhaamdath. It was intended to be a pocket plane used as a safe refuge. It could be accessed only through a portal at the palace of Naarkolyth.

Dhinnilith was destroyed by the tidal wave sent by elves in ancient past during the fall of Jhaamdath. The city's only remaining inhabitant was a ghostly cloud with thousands of human faces, silently screaming in terror.
