The plot:
- uses many WA trilogy characters and places, and introduces even more new ones,
- starts in Wonderland, but after some time everything moves to the new realm,
- needs some WA trilogy characters to be introduced in the new realm.
The longer I think about it the less sense it makes. Can you imagine eg. Professor Blastazar living in non-Wonderland realm? It's like you met him on Barren in PotZ and he said you he had a house there.

I thought of few possible solutions:
1. Remove all WA trilogy refferences and start completely WA-independent plot (what I wouldn't like to do).
2. Make the story take place in the new realm for all the time, but with WA characters living there (to me it makes no sense).
3. Make the new realm a part of Wonderplanet, but far away from Wonderland continent we know and make some WA characters live there (but not the main ones, I wouldn't make eg. Morklin live there; still makes little sense to me).
4. Construct the plot in a way that doesn't need WA characters to live in a new realm and tell that they were asked to go there (hard but possible, for me the best avaible option).
What do you think?
