A race of huge space octopi that live in The Void. They float around in space and defy gravity, so they would float even in air as if they were in the water, except that there is no gravity in The Void. No one quite knows where the Mesinja came from, or how they got into The Void. Mesinja spray out a burning and poisonous acid-like gas (coloured black, and would appear as ink at first glance) when it's disturbed by something.
