Spies Grave

Spies Grave is a nickname given to the planet Arsenal III in the Arsenal System. In the time since the Arsenal System became a part of the Union after the Fourth Intergalactic War, a large number of spies have been captured and killed there.

Supposedly there have been three spies that managed to escape with information taken from a supposed Seenian Depot on Arsenal III. Two were killed when their ships were destroyed prior to reaching Threshold speed. The third escaped with what he thought was plans for protection from Translocator Cannons. When he reached his contacts, it was revealed that what he had was simply a copy of the steps needed to become a Union Member.

The only things on Arsenal III is a large PSI Corps and NAVINT training facility that often has the benefit of training on “live” spies. Part of that facility includes an entrance to the "Seenian Depot."
