The Elder Scrolls: Tamriel

In the heart of Halcyon Lake, the sunken halls of Bisnensel remain hidden beneath dark waters and deeper histories. Founded by Ayleid refugees fleeing the fall of Nenalata in the First Era, it was ruled by King Laloriaran Dynar, the last of his kind. Though once a marvel built both above and below the water, only its submerged passages survive. Between 1E 453 and 460, a Hermaeus Mora cult led by High Priest Uluscant challenged Dynar’s rule, sowing madness and bloodshed until the royal line was exiled. Centuries later, in 2E 582, the ruins became a battleground between the nereid-worshipping Rain Disciples and the Primeval Seekers, who served the Daedric Prince of Knowledge. Lorelia, a nereid, sought to preserve the lake’s waters through a magical artifact called the water stone, formed from her followers’ memories. The Seekers aimed to disrupt her and erase her influence.
