New Graia

New Graia is a completely indoor Forge World that was created after the Ork Invasion of Graia from the Segmentum Tempestus after the remains of Graia were destroyed to prevent evidence of the Ork Invasion. The world itself is similar to Metamor and Redwall in its production schemes, but is completely built around a star, so it is not just a Forge World but a Dyson Sphere. New Graia is owned by the Imperium of Man, and is headed by former Space Marine Titus, as well as being home to Billions of Tech Priests. Every single person who lives in New Graia is a Human, and New Graia have frequently squabbled with the Animalium of Redwall, this caused an event called  Bloody Wednesday .
