Glenn's Eberron Campaign
The Island of Seren is a fairly large island off the west shore of Argonnessen. It is home to the Serenese, a wild, savage, and barbaric people who revere the Dragons of Argonnessen as gods. They are very harsh, tall people who are fond of tattoos and using Dragon materials (shocker, I know).
The Serenese have their own language and often speak Draconic as well. They are often depicted as cannibals and apathetic murderers for their constant raids on all of the other continents. Peaceful contact with them has been little if at all, all attempts to trade have ended in no survivors except for one. One man has traveled to Seren AND come back, a professor at Morgrave University.
