In the spirit world where all of the spirits go Morganthe uses there spirits destroy the spiral and spirits of the legendary wizard trains you new spells to defeats the spirits of the bosses you defeated and you stop Morganthe once and for all to save the spiral from her evil
Great idea, but if it does come out it probably wont be the next world since theres a new world coming called "polourus" (not sure how to spell it) so maybe after polourus your idea will cometo the spiral
