The Temple of the Sea is the underwater temple of Neraeos located alongside the meric city of Riparium. It rests on a submerged volcanic mountain overlooking the kingdom and is a sprawling temple complex that houses various cults and sects while being guarded by Triton warriors.
Unusually enough, the decapitated head of Asmodron can be found here, enchanted to never decay nor be grasped by any other.
