Mianite AU versions and why
Basic synopsis on what I think happened to the AU people: when dianite was assassinated the four grouped up (with their own reasons) to find the killer, au wag joined them later for the journey that took several years. But as they were heading back au wag slipped up to reveal that he was the killer and that started a battle that when wag tried to kill everyone, he used the wrong spell and pulled them through to the mianite world in season one and at the same time that the real Jordan, Tucker, Sonja, and Tom were jumping into the void. So now they have traded positions where everyone is confused to what happened and the dagrun versions of the heroes are trying to catch wag with the help of mianite and ianite. Whereas the four mianitee heroes are trying to get things back the way they should be for dagrun including reviving dianite. While in the original mianite world au wag goes to revive that dianite with the (forced) help of furia.
Future tings via this scenario:
That scenario could have many different outcomes, two of the larger ones that I could see happen are; the original mianite cast go back to their world to find it almost completely destroyed and the two versions have to work together to take down the evil wag. Or the dagrun versions force the evil wag to send them all back and it gets complicated as the evil wag gets free and causes many more problems
