Sanctuary Fortess

The Sanctuary Fortress was a military base used by the Luminoth to create secret weapons systems such as the Light Beam and the Dark Beam. The Luminoth also hid their third planetary energy controller there, and placed a powerful security drone, Quadraxis, to guard it. However, Quadraxis was possessed by the Ing, and took the energy to the Ing Hive. With their base crippled, the Luminoth retreated into the Great Temple to wait in slumber until the day came that U-Mos would awake them.
