Neverwhens are alternate timelines in the Wasteland. Some resemble locations throughout other dimensions in the Disney multiverse, but the events that happen in them are what might have resulted in the original locations had one or more events gone differently. Others are entire places that could have come into existence somewhere else in the multiverse but didn't. An example would be the much more dangerous and hellish version of Wonderland in the 1939 attempt at making the film, where the Evil Cheshire Cat dwells.
This concept was invented by the person who started this wiki to explain the discrepancies between the "Hercules" film and TV series and allow ideas abandoned from Disney theme parks to appear in the Wasteland.
