Kind of curious... but what real-world cultures influenced the factions of Pendor? I can guess that Sarleon is based on Britian (the longbowmen and the lions on the heraldy) and Fierdsvain is based on Vikings... the Empire is based on the Romans, and D'Shar on... well, not sure specifically.
But what about Ravenstern? I can't really think of anything that relates to them.
