Butterfly reign + Willow OC

(A/N: I'm just doing a rewrite of the butterfly reign au of the Dream smp for fun and to add my oc into it, I take no credit for coming up for this au. For the original plot I'm going to try to follow goes rightfully to the author. Since I've not read the book I'm using YouTube for an idea of what's going on so I don't know the author name if you know please say it in the prolog to let me know and give them credit)
