The Last Parsec: Mysteries of Eris Beta-V
Midnight Rose is an old, well worn ship that has seen many owners and extensive modification over the years. A common Grendel-class transport, it was designed for light cargo and passenger duty needing a minimal crew (though with bunks for more). After a decade in the hands of Captain Graham Jacobi the ship has been modified and customized dozens of times, but cleaned less than twice. It may look like a derelict from the outside but she has it where it counts.
Even apart from the dirt and corrosion, Midnight Rose is less attractive than most Grendel-class ships because she is missing much of the hull plating that covers the engines and general systems. During his continuous tinkering, the captain spent so much time removing and replacing hull plates that he eventually just stopped putting them back on.
