Davey Jones is the ruler of the underworld below the sea of Tamir and the Northern Sea east of Serenia. Those who drown at sea join him in his locker, where they will say hello to him.[1][2] His locker is the sea itself.
Behind the scenes
Davey Jones is mentioned if you drown off the coast of Tamir, or in the sea in KQ5 floppy. It is based on the legend of Davey Jones, an aspect of Satan who takes the souls of those who drown at sea.
