Void Gate

From Tardis Wiki, the free Doctor Who reference

The Void Gate was one of the two entrances to the Plume Coteries' Library that was monitored by the Bookkeepers. Where the Cosmic Gate admitted visitors from the Third Universe, the Void Gate opened out into the Void and thus admitted visitors from the wider Omniverse. Like the Cosmic Gate, it led into a Gate Room. (PROSE: The Cactus and the Corpse [+]Loading...["The Cactus and the Corpse (short story)"])
