Prosperan Realm
From Warhammer 40k - Lexicanum
The Prosperan Realm was an area of Imperial space. Once the Thousand Sons Legion's domain during the Great Crusade, it was lost to them in the Horus Heresy, after they were declared to be Traitors to the Imperium.[1]
In the wake of the Great Rift's creation, though, the Daemon Primarch Magnus has begun building another Realm, known as the New Kingdom.[2]
