The End

The End is a completely empty, infinite white void of absolute nothingness, and is believed to represent the end of time itself throughout the known multiverse. Much like the Light dimension, almost nothing is known about the End, although it seems that time travel is incredibly difficult once a person is in this time period.

When the Legends were dumped in the End it took the combined effort of the Monolith and Marcus Allen's speed to escape the End.
