Void Ship

“Void Ship” was a term for a vehicle designed to travel from one world in the Multiverse to another by passing through the Void Between Worlds.

The Fog Ships used by Clockwork Cherubs were a type of Void Ship. According to Pythagoras-858, “competently-built Void Ship” had “some kind of built-in time-space perception alignment matrix”, allowing them to perceive the space around them in sync with other consciousnesses travelling through the Void; otherwise, since the Void had no inherent reality, two different Void travellers could phase right through each other.

When her Shifting powers were destabilised by the Rifts crisis, Jenny Everywhere accidentally shifted into a Void Ship while it wa in flight in the middle of the Void, namely Pythagoras's. (COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids)
