I need trigger help

[Bloody-Bow]

I have 2 different bases and a hero selection. If you select a good guy hero you go to Mithril Hall, and a bad guy hero you go to Menzoberranzan. How do I edit forces determining who enters those regions? If player one picks a bad guy hero it puts him in Menzoberranzan region and he gets attacked by the base because he is on Force 1. I want as soon as all 5 heros enter the region, it allies whichever players those are so they aren't fighting the wrong people.

Or if you could do it a simpler way like if player one tries to go to a bad guy it says Sorry you are a Surface Dweller and cannot select a Drow Hero. I haven't completely figured out either one of these yet so any help would be great. Either limit which heros a force can select or change forces upon entering a region. SOME ONE HELP PLZ it is driving me nuts. Thank You
