A holographic picture of Aqueoses.
Aqueoses are Atlanteans who have been converted to vampires, they were thought to be extinct but have recently resurfaced. They have all the abilities and weaknesses of a surface-living vampire.
They can convert Atlanteans, humans, dylanuses, merfolks and other sapient species into vampires much like their surface cousins. They have the advantage over the surface dwellers as sun-light can not reach the deepest depths of the ocean.
