    Summary

    Betrayal and deception are the order of the day in the state of Undertail, located in the Underverse. A state where there are small rural towns of poor people and cities with rich or middle-class people, but in this story, we're going to focus on the tale of a particularly imbecilic group of idiots, who will suffer on hands of the rich:

    King Ganz of UnderToes
    The Lord twins of DreamTale.
    The Unknown King of Underverse, Cross.

    and the worst of all...

    Landlord of the nine mud pots, Ink Comyet of Underverse.

     

    +++++
    Just to clarify, I'll be adding tags as the story goes on, but I think I already added the important ones, most of the new added tags may be from characters; there will be no gorey violence, just dumb silly violence treated as serious, no explicit sexual content because I don't find it that interesting to write, and I think that's it.

    I'll be updating whenever I feel inspired or I have time, because I'm soon to go back to college and I may not have much time anymore, therefore, if I DO update, it may be short, I just wanted to clarify that so you guys don't feel too annoyed at the wait for a short chapter.

    Summary

    Not all of them are my best work, I rushed through a bunch just having fun with writing them in-the-moment. But still good, and some will be better than others ~☆
    There's quite a few non-con one offs posted here. But not all of them are non con!
    If you don't like non-con, be careful! I'll try to have warnings at the beginnings of each chapter!
    Hope you enjoy ♡

    Summary

    Once again I'm participating in the Rarepair New Year event, hosted by the wonderful Kamari!!!

    As always, this is a collection of random ships and prompts/tropes, ranging from sweet SFW fluff to tasty NSFW smut. Expect a lot of Sanscest, but also some Papcest and cross-AU Fontcest. Individual ships and ratings can be found in each title.

    I hope you'll like these little stories!

    Summary

    Another day goes by working with Dream and Ink

    Another day dealing with his brother

    Another day he gets left behind

    Another day and he's room is being occupied by another swapped variant

    ..

    Wait why is there another him in the stars base???

    ____

    Ink and Dream abandoned Azure in another collapsing AU but when he returns to the base, he finds his area is occupied by another him but smaller and looks like an absolute nuisance with how much positivity is radiating off him (makes sense why Dream would pick him for his energy)

    He goes to talk about it with the others of the group, but it turns into a big fight which leads blue to be trapped in an isolated AU left to die till someone from the shadows goes to pay him a visit

    Summary

    Scrapped scenes that didn't make it from the main fic.

    "Working through issues with a shunned Die-ty" (pun-intended) will be updated monthly unless something happens to me.

    I don't know if it will be at the start, or end, or middle even! Of the month but it will. Episodes of productivity may not apply.

    Comments feed my ego and get ideas out faster Idk what to tell you.
