my idea is about a new world were you have to defeat 3 witches to save that place in the spiral. the place would have 4 places to it they would be:
howling forest. it would have dead trees everywhere and owls would swoop down from the sky and attack.wolfs would howl and some times you would need to fight them.
graveyard of the dead. a graveyard were ghouls and ghosts. in this place you fall down a hole and meet the king of the dead!
vampire camp. a camp were vampires drain the power out of wizards.watch out!
cauldron castle. the last dungeon were you finish the new world and defeat morganthe and the 3 witches.
you get to the new world at level 100 and to get there you must have your level 98 spell. the new world is not a side world.
