Discovered by High Priest Bjorn during a deep-sea expedition, this natural cavern became sacred when multiple followers experienced simultaneous visions of the Kraken's power. Ancient Norse runes found within the grotto seemed to predict the Thralls' arrival, leading them to believe it was always meant to be their spiritual center.

The cavern walls are lined with bioluminescent organisms that pulse in patterns resembling ancient Norse runes. Seawater flowing through specific channels creates haunting sounds reminiscent of whale songs, believed to be messages from the Kraken. The location seems to enhance the connection between the Thralls and their divine beast, particularly during the dark of the moon.

Serves as the primary sanctuary where the Kraken's Thralls conduct their most sacred rituals and receive divine guidance. New members of the faction are initiated here, and important prophecies about the Kraken's will are interpreted from the patterns in the bioluminescent walls.
