Summary
When Frisk had completed a pacifist run the king let them exit through the barrier… no one could have known what would happen…
The core lost power slowly… no one knew why. The royal scientists work tirelessly for years… nothing could hold enough power… not even the human souls that could only power a few machines.
Endless cold… all liquid frozen over… monsters evacuated.. most didn’t make it… others still missing…
Ice and snow consume those who made it far enough for it to corrupt… ice shards and snow grow out of their bodies ether from past wounds or they use their magic too much and it amplified the growth of ice…

Off-Script Storyshift by Logi87

Summary
In search of a missing relative near Mt. Ebott, Frisk falls in the Underground. What should have been a short stay soon turns into a perilous journey through places far different from what they expected.
Note: This story is my personal interpretation of Storyshift. It includes some heavy headcanons that diverge from both the Pre-Boot and Reboot versions of Storyshift. I am using this AU as a creative sandbox, so please keep that in mind while reading!
Check out the original by Voltra here:

Summary
Two years after the events of the true pacifist ending the player did something incredibly risky. With Chara's assistance, they were successfully able to reestablish a connection with Frisk, but this had unexpected consequences. It caught the eye of a threat far more dangerous than anything Frisk, Chara, or the Player had ever seen before. It captured one of them, and gave the other two a choice, save their friend and convince them to change their mind, or watch as the entire universe is annihilated.

Summary
Rather than the selectively mute child who let things flow without any thought of disturbing the pre-established script, it was the mafia boss (in training) who descended to the UNDERGROUND instead.
And Sawada Tsunayoshi never like it when someone tried to chain his will down like a mere puppet.
