Hive of the Glowing Sea

The Hive of the Glowing Sea is a Black Spiral Dancer Hive just off the islands of Novaya Zemlya in the northern seas of Russia. A nuclear sub sank there in 1983 and the Black Spiral Dancers have taken up residence in the land nearby to be near the sub, which has been magically sealed to make the air breathable and turned into a shrine.
