The ScarletSwap multiverse

'''the multiverse is in terminal, universes are being destroyed faster than they are being created. the humans and monsters that once inhabited there destroyed AUs are shot out into the anti-void without any sense of identity or awareness. these abandoned souls were soon corrupted and joined a allegiance which included many of powerful evil sanses.'''

'''the star sanses (ink, Swap and dream) have no idea about this allegiance they have formed, but do know about the multiverse crisis. so they all split up trying to find the lost souls and return them to there homes,'''

this is were scarlet comes in, he might just be what could stop the crisis for good.
