Neithreth is a seaweed-choked bay bordered by mangrove swamps. The bay did not always appear so overgrown with underwater vegetation. Until the 1300s, it had several villages and towns of the Spirachiln along its shores. When the Tendrils, ever-expanding, reached Ralvalloth, they were warped by ancient powers. The cultists of Cheldremn claim the Tendrils were chaos-infused, causing plants to proliferate rapidly and grow larger, shifting in hue, and then becoming otherworldly.
By 1390, the bay was so choked with seaweed and vegetation that navigating the area by boat had become a laborious undertaking. It was also during this period that substantial numbers of Graagvrii commenced settling in the region. Around the Year 1410, the tritons of Caradruk initiated a campaign of raiding the villages and towns of both the Spirachiln and the recent arrivals. Ultimately, by 1420, the Spirachiln had completely vacated the locale.
In the depths of Neithreth lie several undersea strongholds governed by the triton barons of Caradruk.
