Does anyone remember the big hype when you got into the Malastaire dungeon, and when you finally came victorious over him. Imagine this before the dungeon you can choose the normal way to go into the dungeon like it is now or have a way so the dungeon is unbeatable, and he flies on that dragon.
Then you go to a different world then celestia. Then maybe Malastaire and Morgant can rule together and it is slightly harder than before.
