Sol Reapa one-shots by alexmarch097 reviews
just a few one shots for my OC of ErrorSans, Sol Reapa. one of the few known as a traveler. that means Sol can move though the void between multiverses. I have expanded this to an ability to move around the entire multiverse, regulating undertale AU multiverses to a 'pocket verse'. this way it is easy for him to go to other fandoms. so large crossovers will happen.
