I had an idea that there could be a rift world (can't think of name) that suddenly appears in the spiral and is a mashup of current worlds in the game I was thinking the first five, wizard city - dragonspyre (and maybe include grizzleheim) this could also be used to add spells called rift spells that are usable by two schools and maybe take shadow pips
ideas could be stuff like the oni pharaoh as a boss which combines krokotopia and mooshu
spells could also be
the clockwork phoenix a spell that would be available to balance and fire
