Roegadyn are pretty interesting Lore wise. The 2 "clans" are almost complete opposites. Sea Wolves came from islands and are fishermen and pirates, typical brute strength. The Hellsguard live inside mountains and volcanoes, they still have their brute strength but they also have learned to use Magic. Roegadyn are also very religion in worship the Twelve, they don't suffer to blasphemy.

I'm not a RPer but I thought I'd throw all that out there.
