Alternate timeline

Alternate Timelines is an alteration or change in the current timeline, causing an alternate reality to form in the universe. An alteration in a timeline is usually caused by altering the past through Time Travel, which manipualates, shapes, and forms the current present and later the future, and giving birth to a new alternate reality or universe.

It is possible to restore a timeline to its original state by returning to the past and correcting the damage from there, restoring the timeline to its original state.
