what are the differences between factions and communities?

A community is a location with people in it. A faction describes the political, ethnic, and cultural state of those people. I fully intend for factions to have multiple communities and for communities to change their faction. Also, plays that rely on two communities sharing a faction are now possible.

oh, the names mudling and grassfolk made me think that it was supposed to be some sort of non-human sentient creatures that some wizard created.

As I said, I’m not sold on the names.

Names seem fine to me.

And what if it’s higher than 5?

Then the communities are called towns or cities, as defined by an earlier proposal

Derrick enacted this “Reached Quorum 5 to 0”, but quorum is 6. I’ve reopened it, along with the two subsequent proposals which Card failed on the assumption that they were ready to process.
