For thousands of years, this fjord served as the hideout for pirates, bandits, the lair of harpies, dragons, and all manner of other creatures. In the Lith-Crillion Era, Varelay sent settlers to Hells Womb. Accustomed to jungle-like conditions, they were Yuan-ti and their Varelay demon overseers; the latter never survived the voyage, each killed or tossed overboard by the crew.
A small village grew up in the caves and crags of the area. By the Horgon Era, the area was abandoned for the richer yuan-ti settlements in the jungles of Saknussem.
By the time of the Great Exodus (998 - 1017), yuan-ti civilization in this area had declined to small clans, their once great cities abandoned. The Rat fjord became a nesting area for predatory birds and dotted with pirate bases preying on the nascent empire of Kal-Oni, rising in the east.
After the Council of Bile came to power, the fjord was dredged so that ocean-going ships could enter the Foronir river. They along with Paradomea, controlling the eastern side of the fjord, built a number of towers and fortresses in the area. The area is so fortified that in the Black Tide War (1465 - 1486), it was wisely blockaded, rather than assailed.
