Seaslayer is a blade that moves unhindered under water and has an unnaturally sharp edge. It is in the care of Savani, caretaker of the dragon sanctuary Crescent Lagoon.

Master of the Phantom Isle

Savani lent it to Warren, who used it when he, Kendra, Knox, Tanu, Vanessa, and Hako were visiting the merfolk. He managed to incapacitate some people of the deep with it.
