Fictional history[]
Blackworld is an alien planet that was terraformed to resemble Earth, but where historical developments that took centuries on Earth occurred there within hours.[1]
The Rigellian colonizer Tana Nile took a sample of Ego the Living Planet and bonded it to the primitive planet Blackworld, hoping that it might aid the Rigellians in terraforming new worlds.[2] Instead, that piece of Ego developed into Ego-Prime, who bore some of Ego's power, and could dramatically reshape matter.[3] On Blackworld, Tana Nile encountered Sif, Hildegarde, and sailor Silas Grant. Ego-Prime proved to be uncontrollable and Blackworld was subsequently destroyed in a nuclear war.[4]
