Is there a set of rules that goes with this? Can someone post them, or link them?
I don't know the mechanic.
There is a link in the first post on this thread that takes you there to Solazy's original work we are just kind of redoing. The basic principle behind this is that any follower on that tile counts as +1 towards majority. Barraks for cities, Outposts (which we are renaming something like unto Theives Wood/Den), and Ranchs on farms.
Tiles play the same way as usual.
