URA's Abandoned Orbital Strike Cannon Base FOUND

Landscape surrounding the Base

Following an expedition in the nether, Pebble incidentally discovered the nether-side portion of an orbital strike cannon after using Xaero's Worldmap's "Cave Mode" feature and discovering a room hidden beneath a lake of lava. Upon using ledger to inspect the mysterious build, Rory was shown to be the builder. After locating the corresponding overworld structure to the room in the nether, the sight that Pebble was met with was the base which the URA used during the third great Realmplex war; as well as the orbital strike cannon that they refused to.
