Reboot Event

The reboot event is something that sans and Chara have to decide between reboot or reset

The reboot event was explained at the end of arc-2

The reboot button was made by whisper or should I say secret as a new thing to the world (it can be only used once), reboot recreate undercore (it took quite a lot of time when everything was done the multiverse was already big).

## What did the reboot cause?:

* The reboot button caused a massive reboot of the **Cosmology**, it was a hard reset, that reset everything that there was. The Au's and everything side of them get back to point zero, while the ones outside the Au's aka the out-codes were rebooted, some got buffed, some nerfed, and it give birth to new out-codes. It also gives some sort of balance in power
	+ This hard reset was fast and no one even realizes that it even happened, as everyone and everything was affected by it, doesn't remember, as to them the new multiverse and its cosmology are just like it always has been, they don't even know that the reboot event rewrites reality itself and change them.
	+ And there is no entity besides the Celestials and **Pillars** that knows that this event even happened

#### What is the cataclysm?:

* The cataclysm is an after-effect of the reboot event, it didn't happen inebriety but as it took some time, the cataclysm is the moment when half of the multiverse was erased just like that with a snap of the finger. This cataclysm caused quite a shocker and panic around as no one saw it coming.

* Why the cataclysm took so long to happen, well here is the real shocker: it didn't take much time it was really fast but to the others that were affected by it it was like it took centuries to happen.

* But the half of the multiverse that was erased wasn't much important as most of them were just integrals timelines that were on the verge of collapse well most of them, and some were just very bad different timelines/universes that simply didn't make sense, and were meant to be erased.

#### Reboot Echos:

* The reboot echos, are the rememants parts a leftovers of the reboot energy that is scatered throuth the entire virtue verse, rebooting things that are long gone, like for example Esmera that was about to die but woken up in Nexus plane, or the night-omnipotent and omnipotent beings that get retconed, buffing or weakingin them.

### What it did to undercore:

* After the reboot happened the story is mostly the same but the difference is that the Fall's players or rather dragons attacked gods 410 years ago before sans "birthday". Sans, Chara, and everyone else that could remember the reset doesn't remember anything that happened before the reboot so in another world they forgot about the reset and everything that he has done. The reboot changes the world and the story.

* Reboot gives a lot of new possibilities like new powers new cultures and kingdoms. The reboot event makes the essence of the primordials can come back and rise one more time, the reboot event also makes a that the timeline changed which gives new worlds and cultures, and also religions.

* After the reboot even though Whisper and Elena have limited their influence over the world, in which they can no longer interfere at least directly, they still have a small influence on the world like making sure that Eliash will die for sure, as well as the creation of an alternate ending where primordials return and manipulated the story so later they would be gone for good (at least the corrupted part of them).

* The reboot even was the reason why corrupted primordials have returned as well as the reason for the creation of the Sara timeline where the primordials have returned and fought, after they were defeated that timeline still exists, and the timeline of arc-4 hasn't changed, the primordial of their timeline did come back, as Eliash made sure that they will arrive at that timeline but he didn't expect that he would lose, and when the primordials arrived in that timeline they had to recreate their body but the cause of that they were weakened, and it was easy to destroy them.

* The reboot event has sealed the ability of Whisper and Elena to in any way interfere in undercore in a witch, anything that happened in arc-3 and 4 was out of control, as there was no Celestials level entity to control anything during that time.

### Can it be used again?:

* It was a one-shot, it can't be used again, as after it was used the reboot button no longer exist.
* Only **Whisper** and a few **Celestials** are capable of creating another reboot button, as they know how the reboot button truly works.
