The Return of the Fallen

It's been years since the barrier between the Underground and the surface was broken. Monsters and humans were finally able to coexist in peace, and Frisk had become a beloved hero for their role in freeing everyone from the Underground.But one day, a mysterious portal opened up in the middle of Snowdin, and out stepped a group of monsters unlike any other. They were twisted and dark, with eyes glowing red and sharp teeth bared.These monsters claimed to be the "Fallen," a group of monsters banished from the Underground long ago for their wicked deeds. They had been trapped in another dimension, but had finally found a way back to Undertale.The Fallen began wreaking havoc across the land, attacking humans and monsters alike. They were determined to take over and rule with an iron fist.Frisk knew they had to act fast to stop the Fallen, but they couldn't do it alone. They recruited the help of their old friends, including Sans, Papyrus, Undyne, and Alphys.Together, they set out to defeat the Fallen and save the Underground once again. But as they fought, they discovered that the Fallen were being controlled by an even greater evil - a powerful being known only as the "Void."The Void had been using the Fallen as pawns in its plan to take over all dimensions, including the human world. Frisk and their friends knew they had to stop the Void before it was too late.In a final battle, Frisk and their friends faced off against the Void in a fight to the death. It was a grueling battle, but in the end, they emerged victorious.With the Void defeated, the Fallen were released from its control and returned to their own dimension. The Underground was saved once again, and Frisk and their friends were hailed as heroes once more.From that day forward, the people of Undertale knew that they could count on Frisk and their friends to protect them from any threat that might come their way.
