Exacting Their Revenge: An Undertale Fanfiction (Echotale Gaster!Sans X Cannibalistic Holocaust Reader) by orphan_account for
Fandoms: Undertale (Video Game)
17 Jan 2020
Tags
Summary
Your stomach rumbled. Making you move ever so slightly. It was nearing your feeding time anyway. You ever so slightly lifted your head off of your battered arms to give an ice cold glare to the glass window that separated your room to the rest of the asylum. The glare you were currently giving the window was one of those glares that could render a full grown man helpless. You smirked once more at that thought. Though this time, your smirk was plainly visible to the people currently monitoring you from the safety of the other side of the glass window you were currently looking at. That's right. They were safe from you with being on the other side of the glass.
Things to look out for:
~ Blood and gore
~ Mentions of violence
~ Cannibalistic notions
~ Horror topics
~ Upcoming intimate scenesWARNING: This story is very graphic, and not for the faint of heart! There are mentions of upcoming rape scenes, graphic depictions of violence, profanity, and a whole lot of blood and guts. This is rated M for a reason. If you have not already read the summary for this fanfiction, I highly suggest that you do. You have been warned, read at your own risk. This is geared for mature audiences only.

Book of the Souls Soulmate Edition: Guide to Understanding Soulmates by Celtrist
Fandoms: Undertale (Video Game)
02 Mar 2020

Summary
The SOUL is a mysterious thing, but for many of the things unknown about it, we are able to learn from it. One of which being the idea of being fated with someone. A SOULmate.
You can use this for your own fic if you want.
Yeah, so, real talk. I sorta got lazy on writing this (couldn't even bother writing a good intro chapter for the darn thing). I may in the future add or get rid of chapters, and maybe you guys can add some ideas too. But again, I got lazy and couldn't think of any more topics to have individual chapters of. It may look a bit sloppy and confusing, and I apologize for that. If anyone wants to redo this to make a more cleaner, organized version, be my guest. As of right now, this is what I have. Now you may be wondering, why am I posting it now unfinished and messy?
Well, gonna be real with you, it's March. My dragon is drunk this month. And I don't know if I'll ever truly finish it and it would be nice to get feedback on what chapters to add and take out. Plus, like I said, Cel is drunk and it's a good excuse to putting this messy unfinished thing out. -

Summary
Your friends had finally dragged you along to an anime convention, and this time, you rolled your eyes and decided to enjoy it. It wasn't that you didn't enjoy anime, for certain manga had you flipping through pages and specific anime had you flipping through channels. It was rather that a convention was a prime location for your nasty little habit to rear its ugly mug.
Little did you know, your kleptomania might actually lead you into something positive for once.

Summary
You are the Princess of Notron, and when you came of age, you were sent to your family's tower to wait for a suitable knight to rescue you. It's not that bad, you have plenty to do and you also have your handmaiden to keep you company.
It got repetitive though, greedy knights coming by to claim you as a trophy, them getting beaten by the tower's resident dragon, and the process repeating itself day in and day out. It was boring.
That is, until a new knight steps forward and is determined to help you solely for the sake of helping you. Impressive and different, the knight even refuses your proposal. That just makes you all the more determined to win their heart.

Summary
In a world where females are scarce and the Monsters are so used to death a young woman is forced to help save them. Although she is not the only one that had been summoned, the weight of her duty is still heavy. Hopefully with a bit of time she will succeed in her given tasks but until then she needs to watch out for those around her. As Monster's of all sorts come to ask to be her mate some don't take rejections so well. Thank goodness though that she has a few helping hands. Well they would be considered helpful if they left her alone for five gosh darn minutes.

Frisk couldn't recall exactly how many times he had been in this same position.
He had lost count on how many times he tried and failed. Lost count on how many times he had died. How many times he had RESET.
It didn't matter what he did, he always ended up failing. No matter what choice he made, he failed.
