I have created two tribes, one with Magic faction and one with Nature faction, and completed all the puzzles for each. Based on the stories told in the cave and the secret room, I think there must be a way to get a woman from one tribe to marry a man from the other. Has anyone figured out how to do this?

that leads us to vv4 mary

YAY VV4!!! Sorry i couldn't help myself. Yep, i think tkdgrl is right, that would be where VV4 starts. It would be cool if you could do it in VV3 though...

Yeah, sorry, there is no way to join your separate tribes in VV3 or get one villager to marry a villager in a different tribe. That story is building up to VV4.

Or, you can pretend to have villagers from two different tribes who marry each other. It's kind of like in VV2 when a couple doesn't actually disappear from your VV1 game and appear in VV2. You just need to use your imagination to make it happen.
