Drowned

See also: Tempering

“

A queer by-product of Leviathan's tempering, the drowned are not only corrupted of mind, but of body as well—their limbs taking on properties most associated with wavekin and other denizens of the seas. While the drowned are believed to retain a portion of their former knowledge immediately after receiving the Lord of the Whorl's “blessing,” the advancement of the transformation appears to result in an accelerated loss of the “self,” culminating in the complete devolution into a mindless thrall.
