This looks like it was a lot if fun! Very cool idea for a scenario. Did you change any rules to make it work?
We used 2d10 becasue the regular game Mike runs on that table uses the d10 and it was easier to use them than to have to pass a few d20s back and forth.
I premade the wizards and two of them were sort of my own creation. The Pirncess was sort of an illusionist even if story wise she was a witch. The inquisitor was loosly based on D&D type paladine.
I also gave wizards a "look out sir" rule... basicly if they had a lacky with in 3" when they took fatal damage they could sacrifice the minion to save the wizard.
