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~!

Summary
Odile is a young woman pursuing a study in astrology when she finds Siffrin washed up on the shore near her home. She ends up growing up alongside the boy, not quite raising him but its enough that the two see each other as family. The island is forgotten, her research collapses and the duo head to Vauguarde in an attempt to figure out what exactly is going on, getting stuck in an endless loop of the same day over and over.
alternative title : siffrin washes up on the shores of ka bue instead of vauguarde.
alternative alternative title : odile is stressed and siffrin is a little shit and they both end up in the time loops.Bookmarked by xenofrin

Summary
In the moment of ultimate desperation, Siffrin sees a future: a new yet untread path to follow. What Siffrin could not foresee is waking up in a body not their own. A different world, with different rules. Be careful what you wish for.
OR
Siffrin accidentally becomes Kris' Red Soul, and is forced to deal with the repercussions of that. The world of Deltarune is very different to the world of ISAT after all.
