It is first seen in Paradox when Professor Paradox was experimenting in his lab when his assistant Hugo drew back and hit the controls, causing the machine to become a vacuum, pulling Paradox inside of it and hurling him into the event horizon of a virtual wormhole. Hugo also is sucked in (and these effects turned him into a time-creature that aged everything it touched).
Some time prior to Ultimate Aggregor, it was rebuilt.
