Summary
After the True Pacifist ending, Frisk begins having strange dreams—visions of places they never visited and feelings that don’t belong to them. At first, they think it’s just leftover trauma… until they realize Chara never really left. Bound to Frisk's soul but no longer in control, Chara watches silently—until one day, they speak. Not out of malice, but out of loneliness.
Now, Frisk must navigate life on the surface while sharing a mind with the one who once nearly destroyed everything. Can two souls with such different pasts find common ground? Or will history repeat itself, one whisper at a time?

To steal a purple soul (And hold it gently in your hands) by Feniksiara

Summary
To hold admiration towards a man who never interacted with anyone was foolish. To want to get closer to him despite knowing what he's capable of was even more so. But was it truly so foolish if her devotion was eventually noticed? Perhaps the reclusive man held more in his heart than cold calculations, if only for one person. One woman, who managed to steal his soul and held it gently despite his crimes.
Or: Reader is determined to help in any way she can and manages to slowly slip through XGaster's walls and into his soul. Neither knows what to do and is too blind to notice the pining. XAlphys and Ink are amused, until they aren't.

Packed with LOVE by UnknownRegion for GenderlessPerson
Fandoms: Undertale (Video Game), Harry Potter - J. K. Rowling
15 Aug 2025
Tags
Summary
Harry loves his occupation as a Special Intelligence Investigator. Basically, it's a fancy title for 'extracting information via torturing prisoners'. He also has a lot of free time to laze. The only downside is that this job causes his reputation to plummet into the drain. The masses know him as the Puppeteer, the Brain Eater, or the Terror Infinity to name a few. But they usually just call him a 'that fiend', which was worse. He is also the partner of Voldemort, the overlord of Magical Europe and reigning Dark Lord. So how did he make a simple mistake such as this? Judging by Tom's expression... He is so dead.
Harry: Can you not disturb me during my break, Tom?
Tom: Am I not welcome, my dear?
Harry: More like I want to enjoy alone ti- oh, shite.
Tom: ... Is it supposed to react this way?
Harry: According to prisoner no. 444, this thing would simply act like a remote nuclear bomb after having magic inserted.
Tom: I suspect that I will regret asking this, but did you at least find it within yourself to use legilimency to confirm his words?
Harry: Eh.
Tom: You imbecile.Cue explosion of epic proportions... and getting thrown into another world via a tear in the multiverse.

Summary
Yeah, it was a good day. Sun was shining, birds were singing, and all in all, you were ready to get to work and stretch your creative muscles.
Of course, you should have thought it wouldn’t be that easy. Some mornings started hard, and ended easy. Some started easy, and ended hard. But they almost never started easy and ended easy, and today was going to test the bounds of your patience like nothing ever had.

Summary
It was 23XX.
The endless expanse of the wartorn, darkened world left nothing in the aftermath. As the (presumably) only two individuals that walk on this world, you and Papyrus kept trudging on. It was you two against the world, after all. The undead - both human and monster alike - kept things ... interesting, but in a void-like world, as long as you had your brother, you were okay. Definitely.
That is, until a sudden break in reality - a tear from a fountain. You didn't realize triggering it would send you to another universe? Timeline? All of this - what is this? What is happening?
(This isn't a Sans/Sans, Papyrus/Papyrus, and Sans/Papyrus story!)
