Random in game Easter eggs threw out vana'diel
Reason: what would be more cool than find something random while traveling threw out the lands. Like maybe a down airship in the middle of no where. Or a random npc, the body of a dead adventure, or maybe a floating castle that shows up out of no where from time to time. Something simple that could be added in with the up dates. Things that don't so much attach to quest but just stir's the imagination.
