Can anyone explain the term "explorable"?
The reason (story-wise) you go to the dungeon is the information you receive about the Destiny’s Edge members going on a certain quest. You help them do their quest and figure out their problems and leave the Dungeon behind (Story-mode) and later you can come back to explore the place after your story there is done, which usually involve some 1-time NPCs clearing up the mess we made, hence Explorable-mode.
During development these paths were described as having different variations to them as they would have random events which would occur. The result was supposed to be that each explorable path wouldn’t be exactly the same every time you ran it. I am guessing that turned into a huge mess or created too many technical problems since it didn’t actually happen.
