Also once we've established who or what everyone is, you should ask yourself where in Everdark do you live? Feel free to do a bit of mini world building with the location as the dungeon is quite literally without end as it leads to the Depths (an uncreative name substitute for Underdark).

You don't own a swath of the dungeon of course, if you wanted to you could try but nothing will be easy for small-fry like you monsters.
