Described as the most beautiful planet in the Milky Way's Orion Spur, Glorisius was only discovered after advancements in drive technology allowed the crossing of the Shade, an almost starless gas cloud in the Spur. Glorisius is the only know source of Glorindium, a heavy element resistant to all known forms of radiation.
The planet's system GLR775, or Endarron, is host to the largest fleet of Sentient Pact warships outside of Sol and Grrwyaha. The planet is not a viable candidate for terraforming due to its crushing gravity, making mining of Glorindium even more challenging than radiation imperviousness alone might make it.
