“

North of the Sharlayan mainland lies the verdant Isle of Haam, a land long protected by the Forum as an academic asset due to its abundant wells of aether. Yet with plenty often comes peril, and the vicious beasts that live there will not so readily relinquish their claim to the island's lifeblood. Will you secure the energy you need to breach the void—or be returned to the very flows of aether you seek?
