The multiverse is a crossroad for a series of parrallel universes. Able to be "stepped into" or "sucked into" via rips or portals. Following information is based on speculation:
- Elements of Discord most likely originate from a dimension similar to the MLP one. And have managed to travel the multiverse with realitive ease.
- Multiverse can be survived by an organic being for an extended period of time, which allows travel between worlds.
