The Vaj was a remnant of the old Thakolarivaj, the "Great Orion Empire", surviving into the late 24th century. Its capital was Vajripam, where the Imperial Palace was located (formerly a Fourth Orion Empire power plant), and it lay primarily on the continent of Ingarroi. With a population of 510 million Orions, it was the largest kingdom on Rigel VII, but was described as sprawling and ramshackle, and it was rent by internal divisions.
