This is a Sanders Sides AU What if instead of splitting just as the creative twins had done two sides became one creating someone knew... (These characters do not belong to me they belong to Thomas Sanders.) What if there was a barrier that separated light from dark sides in the mindscape. What if this barrier was two sided protecting both sides of the mindscape from each other. One side guarded by a kind, caring side who could never hurt a fly. The other side guarded by a vicious, unforgiving side who had never shown kindness to anyone or anything. What happens when one of them begins to fade. Will the other take guard on both sides or will they find a knew solution. -warnings- Mentions of fading, death, and blood ~Sorry for any spelling or grammatical error it may have~
