MMORPG.com has recently published the first of many in a new series of dev journals written by the Lead Game Designer: Chris Nengerman. Nengerman talks about the challenges of creating instanced dungeons.
One of the more interesting parts of this is that the areas lore is separate from the main storyline, and thus making the quests like a mystery story in the game.
-Note to self- Don't play in the dark at night alone.
