Summary
Burgerpants is only 19, but his life is already over. He works a dead end job as the cashier in a fancy hotel run by his intimidatingly-hot robot boss, who constantly berates and insults him. His only chance at friends is the weird kid that sometimes visits his stand (not bad company actually, but how much of a loser do you have to be when your only friend is eight years old and doesn't even talk back to you?) His love life is an active disaster. The one time he tried love, he was shoved in the dirt. And that solidified one thing: Pretty people can't be trusted. But when a brighteyed, cheerful vender from across town comes to visit HIS shop, everything changes. Now BP has to balance his job with his relationship, but it's not as easy as it sounds. Between his hot boss and his own issues, can Burgerpants actually keep his life afloat, or will it all come crumbling down?

Summary
This the story of Kingdomtale, an au I created that's essentially Undertale if it took place in the medieval century. It's not historically accurate but it's my take on this popular concept. I have already posted a series for this au but have grown dissatisfied with it. I know I can write something better. This is the new and improved Kingdomtale, and it's going to come back even stronger and better than before. My hope is that this story can feel nostalgic in a way, like you are experiencing Undertale all over again for the first time.
Here is just a quick snippet of the plot: The year is 15XX, and another human has fallen down Mount Ebott. This human is no more than a child, having woken up in a bed of golden flowers. How did they get there? They'll soon discover a world of monsters, magic, and much more. Can one human child bring peace between two different races that have been forced to share one Kingdom? Well, you'll just have to read to see if the story is still as you remember it.

Summary
Kris was done. After a couple life-changing months, the Roaring was gone and the Angel was banished. They would need time to process the new happy life they now lived, and time to grieve the interdimensional invader they had grown so attached to, now separated from them. But first, it was time to check up on how hometown had changed after experiencing the Roaring and the power of the Dark Worlds.
Meanwhile, Ralsei is very confused as to why the narrative still feels like its moving. Weren't they supposed to reach an end? With their connection to the upper layers cut off, what could possibly be keeping things moving, and what did that mean for them?
This work is based on the events of Persistent Variables by BewareTheDragon1. It takes place the day after chapter 99 (so, before the actual epilogue).
