The Faction system shows the fickle nature of those vying for your affections (Wyrdstone). Each Faction has its own separate Faction ranks and once the rank goes up for one Faction, the other 2 Factions will offer more gold for the same weight in Wyrdstone. Furthermore, once one Faction rank goes up, the other 2 Factions will require more Reputation to increase in Faction rank.
You build Faction ranks with Reputation which equals the weight in Wyrdstone that you ship to that individual Faction. Doing so gives Reputation Bonuses according to your Faction rank.
