Usually, when a basic plane is first born, it has only one time axis, which is known as the main time axis.
Apart from the main time axis, other time axes might also emerge within the plane due to certain special reasons.
For example, a powerful entity might penetrate time, return to the past, and alter the outcomes of events that should have occurred. Such changes to events that have already happened can have a massive impact on the continuity of time and usually result in two outcomes.
One outcome is that related seals on the main time axis are erased, like if someone's parents were killed by someone who traveled to the past, then on the main time axis, that person would be completely erased, to the extent that no one would remember their existence. This erasure occurs because their existence violates the Time Rules and can only be erased by them.
