For your own safety you run away to the depths of Mt. Ebott in hope that the legend was true. But once you fell down you start to realise that this may not be the first time... "You've been here before, Y/N. And this time I won't let you run"

Fall of the Empire [ Sans x Reader ] by morrow-

You weren't quite sure what you were. As time progressed, you had been called many things. Hope, future, a new beginning. You weren't quite sure why they called you those things, for each passing day you say locked in a cell, waiting for the freedom that would never come. You weren't alone. You grew fond of two other experiments whom you nicknamed Sans and Papyrus. The routines seemed to grow normal, coma-induced trances, painful tests... And then nothing... One day, the pain stops coming. Slowly, the three of you venture outside of the prison and discover that there is a world beyond the cell.
