After what appeared to be just another day in Snowdin, Sans finds his day turned upside-down when figures kidnap his brother and send him through a portal. Following their trail, Sans explores this parallel world while being accompanied by a purple pony searching for her way back home (and also seems to literally be incapable of not asking him questions).

A fic I've had on the back burner for quite some time now. Continuance of the story depends solely on feedback, despite having a relatively clear picture of where the story goes from here.
