UE-14

"About 24, 25 years ago, a neighboring Earth invaded our planet through a breach and almost destroyed the place. So to prevent it from happening again, they banned all inter-dimensional travel. And then they put the Collectors in place to punish those of us who violated the ban."

- Harrison "HR" Wells

An undesignated universe was one of the many universes in the Original Multiverse. It was destroyed during the Crisis.

History
In around 1992 and 1993, the denizens of this undesignated universe discovered a breach to their neighboring universe of Earth-19 and invaded it. This resulted in the near destruction of Earth-19 and the formation of the Collections Agency, along with the ban of inter-dimensional traveling.

On December 10, 2019, like other universes in the Multiverse, this undesignated universe was destroyed during the Crisis.
