Base Prime, a research facility, was established by the Marvid and Craitheus Qreph. Its location was within the Bubble of the Lost in the Chiloon Rift of Wild Space, specifically on a monolith of unknown origin. The laboratories where the brothers performed their experiments were situated inside this installation. Following the successful rescue of Han Solo from the Qrephs by Luke Skywalker, Leia Organa, Lando Calrissian, Ben Skywalker, Omad Kaeg, and Tahiri Veila, it met its end in 45 ABY.
