Summary
“They’ll never want to travel with me. And even if for whatever reason they do, they’ll leave.” His smile was starting to get really unnerving. “If they ever find out what I’m really like, they’ll hate me, and leave.”
Siffrin laughed again. “But it doesn’t matter anymore. I’m stuck because my wish is fighting the King’s wish, right? I think my wish is taking priority over the King’s since it’s more recent and has more intent, but if neither wish can be fulfilled, then there’s no way out.”
“Surely you could just ask–”
“If neither wish can be fulfilled,” Siffrin continued, talking as if Loop didn’t even speak, “then I just have to break the wishes.”
(An ACT 5 scenario where Siffrin realizes that the only way to break a wish is to erase the wishmaker, and Loop must do whatever they can do stop them.)

Summary
A Tale of Stars And Time is a crossover AU/AT that combines both Undertale and In Stars and Time. Originally inspired by a few memes/fanworks of Siffrin in Undertale, this concept does exactly that – take the characters from ISAT, shove them into Undertale and see whatever the heck happens next.
The general plotline involves Siffrin going through their usual time looping shenanigans in their own world when, mysteriously, a strange grey door appears in a hallway that definitely wasn’t always there. Upon closer inspection, Siffrin and co. are suddenly thrust into the very beginning of the Underground. They are soon met by Frisk, a strange child with more to them than meets the eye. Now, the six of them will journey through the Underground, meeting familiar friends and dangerous foes, with plenty of surprises along the way.
A new play is about to begin, so get on stage, stardust~!
