End of the Pre Eras

No one knows for certain what this disaster looked like, only that it engulfed the Scrapbook once before, leaving little survivors.
Funny thing about these survivors: there was a pair for each of the 15 planets, and each suddenly discovered that they had magical power, perhaps something similar to Ancient Scrap Magic. The survivors, called The 15 Pairs of Divine, were then worshipped as deities after they'd restored the Scrapbook to what it was before, and started the First Eclipse Era.

While it was believed that these 15 pairs couldn't die, and would protect the Scrapbook for the rest of eternity, this was not the case. The 15 pairs often fought, until only one was left. This one survived because they didn't participate in the fighting. When the last of the 15 Pairs of Divine died, the First Eclipse Era ended.

Manifestation

Not much is known about this Era-ender disaster, as it has only happened once and all the beings who might have been there to witness it are dead. However, what is known is that a giant eclipse happens and blots out all light, allowing all hell to "break loose," so to speak. We do know for certain that numerous holes to the Rift open up, and many creatures and anomalies crawl out to attack. We have the Rift Sickness to thank for having no more Rift anomalies right now.

Localization

While holes to the Rift is something that happened across the entire Scrapbook, it is said that an imbalance or complete shifting of any magical properties of the 15 worlds occurs. Herudumra becomes too hot, Drimori has an increase in magical power which upsets every creature into using said power, which eventually tears the planets apart.
