In the Demon Spawn War (8972 GE - 9493 GE), two great lords vied for control of the Imgangreth region. These were Tarâk and Blibdoolpoolp, two more interested in building a worshiper base than the great war around them. They were competing for those living in the subterranean reaches, both wanting the divine power that comes from being worship. In Imgangreth, the final battle between the two was the Battle of Dream Madness. Defeated in this battle, kuo-toa legions under Blibdoolpoolp fled by the thousands through the Murkin Channel. This open rift carried them thousands of miles away to their new home. Blibdoolpoolp left them to their own devices, to rebuild their numbers. Up river of lake Fishur, they founded Fongruk-Toa.
Devoted to Blibdoolpoolp, Fongruk-Toa and the settlements she spawned, were instrumental in Blibdoolpoolp's Ascension (19 Dreamer 9480 GE). The original intent for building Fongruk-Toa was to serve as a temple to her. As time passed, the temple grew in size, as did the number of sacrifices. When they could not find humanoids to sacrifice, they had to give up their own or raid other kuo-toa settlements around Fishur.
In the First Epoch, Fongruk-Toa returned to their early beginnings, distant descendants raiding the shores of Lake Murkin. In Year 409, Fongruk-Toa forged a military alliance with the illithid leadership of Ginrall. The goal of both parties was the capture of Elalmoth. After the fall of this city-state, the kuo-toans turned on their Diortfel Pact ally. The conflict between them ended several years later with Ginrall giving up any claim or use of the Murkin Channel.
Fongruk-Toa spreads from the shores of Fishur to deep underwater. Many of the underwater buildings have pockets of air or have air circulated into them. These areas are usually places for air-breathing slaves. Fongruk-Toa's slave population is about 40% of its population.
