Since there are so many factionless, maybe they could join the other two later on. How do they learn about these things, anyways? Where's the registration form? Are there door-to-door salesmen for them? Do they have yard signs?

The big three factions usually recruit through the properties they own. Each of them distribute plenty of propaganda explaining why [i]their[/i] philosophy is logically the best, and why anything else would result in undue suffering and universal destruction and all that jazz.
