Time travel

Time travel is the magical ability to travel through time. Travelling through time usually comes with certain rules and restrictions and it can be quite dangerous for those who are inexperienced. Nearly all Mugens have the ability to time travel, usually through the use of the Shardis.

Uses
Mugens use time travel for a variety of reasons.

Fated Time Travel
While some may consider it to be changing the past, it appears that unless a time paradox is involved, all events are destined to happen. This means that if someone were to go back in time in an attempt to save a loved one from dying, they would always fail, as their loved one had already died, meaning they had already went back into the past in an attempt to save them and failed.

Clock Notes
Mugen often leaves his past self hints in the form of notes from his future self. While this seems to be an incredibly helpful use for time travel, Mugen only leaves clock notes under very strict rules. He does not lead his past self to make discoveries he could not make on his own, and he does not lead his past self to creating an alternate future or time paradox. This has caused many to ponder whether or not clock notes are actually necessary at all, considering if Mugen could come to these discoveries on his own, the use of clock notes is pointless. Many suggest that Mugen merely restricts himself in this way out of fear that his past self may become smarter than his future self.
