Hildaland

Hildaland is a mystical underwater kingdom that has existed for almost as long as the ocean itself, it is the home of the Selkie race and sometimes surfaces as a shifting island that sinks back beneath the waves after a short while. Few mortals have ever seen this mystic realm and none have so far set foot on it - originally a tranquil realm akin to a paradise it came under attack from the Nuckelavee in centuries past and was saved by the Seal Maiden.

Yet despite her bravery Seal Maiden was powerless to stop Fisherman from reviving the Nuckelavee and once again enforcing his will upon Hildaland - prompting the events of the "Message In A Bottle" storyarc.
