My character: Greek warrior returning home from the Trojan War. His ship stops on strange island in the Mediterranean or a storm wrecks leaving a few survivors stranded. Doesn't have to be completely like Homer's Odyssey with Cyclops, Sirens, Lotus plants and/or Medusa.

Or we can relocate an Odyssey type story set during the Crusades with a European knight heading home after battles in the Holy Land.
