Crey

Crey is an underwater location, likely the site of a sunken city. It was the place of a battle between the Slithereen Guard, led by Slithice, and an army of marauding Levianths, seeking to plunder its sunken treasures. Although the Levianth army was eventually driven off, a single chalice was found missing from the vaults of Crey, leading to Slithice being banished until it was recovered.
