The next room on the left also appears to be some sort of quarters.
In this room is its former and current inhabitant. An Ancient Ophidian Mummy.
This mummy is ancient, really ancient. The necromantic forces that are natural to this area affected this ophidian officer. He is powerful but quite insane. In this room, he is powerful (8 HD) but once he leaves he drops to 5 HD, if he leaves the ship he drops to 3 HD. So for the last few centuries he has been sulking here.
As an Ophidian Mummy, he does not have the Mummy disease as do standard mummies, but he does have a poisonous bite. It causes 1d4 hp damage, but victims have to save vs. Death or take 4d8 hp damage (save for half).
