The Guardian Monastery
Maybe this monastery has already been raided by the forces of the tyrannical empire and they have left some robots to guard the site in case someone still wanders there. Or perhaps there are still some brave space knights hiding in the monastery (perhaps they have even started to lose their sanity for some reason?) and guarding the last pieces of the valued crystals and old archives that were not destroyed in the Great Purge.
