The Fortress was a cave on the planet Jelucan, named such by Ciena Ree and Thane Kyrell. The two friends spent years furnishing it with fur rugs and blankets from Ciena's family, and luxurious castoffs from Thane's. The cave was positioned less than fifty meters from the Kyrell family's hangar, but because it was hidden between two outcroppings, it went unnoticed.
