The Oblivion
The Oblivion, also known as the Eternal Oblivion, was a place or state of existence to which one could “fall” after being erased from Time.
Lord Thymon once gave a seminar entitled How to Earn a Steady Living by Crushing Universes Beneath Your Proverbial Feet and Casting their Residents Into the Void of Swirling Oblivion. (PROSE: New Warehouse To Be Constructed In The Homeworld)
Acantha managed to avoid falling into the Oblivion completely by making alterations to the timelines on her way “down”, setting the stage for her return. As a result, her essence became suspended in a state of half-existence on the fringes of the Oblivion until her Cult arranged for her restoration. (PROSE: Century Smith and the Time Terror)
Behind the scenes
The Oblivion appeared more prominently in the earlier The Crew of the Copper-Colored Cupids story Stranded at Memory's End.
