What are dead Factions?
Dead Factions are Factions (like Gondor, Dale, etc. (Do not mistake them for dead, with this I mean, not Pacts or such, but Kingdoms, etc.)) which do not exist any more, or have been destroyed during some War, or all Members including Leader have been inactive or abandoned it.
