Fishur is an Underdark lake of Anulu. It is home to numerous kuo-toa and scrags. Many of these predators are citizens of Fongruk-Toa.
In the northern part of the lake, at a depth of 2500', is the Murkin Channel. This intra-system rift serves as a link between the waters of Fishur and those of a far away surface lake named Murkin. On the Murkin side, the rift also provides access to the Underdark reaches of Garathral.
