## ***The Eras***

There were a few different eras which have been brought upon.

### *The Nothingness Era*

**Timeperiod:** ???-0

This was the time in which thoughts were forming, minds were gathering to create the first incarnation of Undertale. This is the Era in which BETA\_Gaster was formed from the BETA of Undertale's first copy, thus making him the oldest being within the fandom.

### *The Era of Creation*

**Timeperiod:** 0-1

This was the era in which the foundations of reality were beginning to form. The Four Pillars of Existence, then Alphatale (should that AU be included as an AU canon to this multiverse, then that is where it would fall in the timeline), then The Formation, and then the first two AU's; (other than Alphatale) Underswap and Underfell. After that came The Era of Dawn.

### *The Era of Dawn*

**Timeperiod:** 1-8,000

This is the era in which more and more multiverses and AU's began to form. It was a time of chaos and confusion and events and all the different things that come with stimulating a layer of existence.

### *The Era of Tension*

**Timeperiod:** 8,000-10,000

During this time, tensions around the Coreverse began to rise, despite activity beginning to slow. No one knew exactly what it was, but this time was filled with a foreboding air.

### *The Anomalous Era*

**Timeperiod:** 10,000-???

The current time.

### *The Era of Decay*

**Timeperiod:** ???-???

No one knows when the fandom of Undertale will perish.

But some say that the existence around the world of Undertale will eventually begin to rot and decay...

Until, with one final gasp, the entire layer of existence related to Undertale will simply cease to be.

Only Fanon!Sans can see that far into the future, and even for him...

*"...just give up. i did."*

## ***Important Dates***

**Time of Occurrence:** 1

**Description:** The Four Pillars of Existence were converted into AU's which wouldn't actually change or have anything happen until far later. Unbeknownst to anyone else, however, Prime!Frisk was semi-existent. Which... Doesn't make sense in the slightest, and thus attracts the attention of Fanon!Sans. He discovered that Prime's SOUL was pulsating. So, he locked Prime!Frisk in a stasis which would allow them to not physically age, yet fall into a slumber which would let them subconsciously roam a different version of Undertale.

**Description:** Decayverse is turned into a sort of Save Star, and BETA\_Gaster takes notice. Thus, he takes Crimson!Frisk and Merlot!Alphys, the two survivors of the Decayverse's existence into the Prismarine as a new home for the two. The Permustellation Star is taken into the BETA\_Archives for safekeeping.

### *The Story Begins*

**Time of Occurrence:** 10,000

**Description:** Sentience, change, chaos... Life.

It is granted to the Pillars. Thus begins our story.
