Looks like this rule is missing a word, perhaps it should be cloud?3. A Major Faction's is dependent on the number of people it has during it's Major Faction Application. For every 5 unique writers, the Major Faction will start with an extra hex, at a maximum of 3 starting hexes.
Considering the most recent app that was accepted had only 5 players, and accorded one hex, that pretty much answers my question. (u Valiens Nantaris )
*Said template also suggests 7 members are required to start, which seems to be inaccurate as well now.
