The Iof is a D'vor ship that the Grob managed to steal. It seems to have some sort of computer running it that they call its "brain", though a computer that's obviously far too small to be able to run a ship and doesn't even have a single vacuum tube in it. There aren't any crew quarters as such in the ship, though, so how the Iof could hold a crew is a mystery. Its current occupants have to clamber amongst conduits, loose cables, and other electronic and machine parts to get around.
As a whole the ship is powerful and has a bizarre modular construction that lets the Grob modify it with enough time. Its armament is based on energy projection and it also has an energy shield of some sort in addition to physical armour plating.
