The wizard101 society should make a new "spirit world" where malstaire is alive and cannot die and sylvia is evil and totally new enemies like fallen wizards or fallen knights of dragonspyre that you never met and when you visit this world you have to find some glowing orb of disastor (sorry if spelled wrong) that turns everything in the new spirit world evil and gives malistaire even more power *resistance to all elements, controlable of every spell, more health and a different look and sylvia helps him.* And make cutscenes for the new world...
I like the ideas! But may I just mention the Sylvia turning evil thing is a good idea but it kind of goes into conflict with Syliva's spirit helping you in the final battle. Maybe, just maybe take the same idea but put a different person in it's place. For Example, maybe other members of the family like a secret brother or Malistare's children(if he had any whats so ever).
