Gallifrey Eight was one of the Nine Gallifreys. It contained loomstacks and chronoforges which threw biodata soot into the air, obscuring the sun over the Citadel. Homunculette and the War King visited Gallifrey Eight after the battle at Delphon. (PROSE: The Taking of Planet 5)

The Instituition for Mental Deviancy was located on the Eighth Homeworld. (PROSE: Eyes)
