Claiming.

Egg mines might be getting new assets/tileset. You can start with it and make it work. But it might be better/easier to just do a cave for now. 

Alright.

All I've done so far is cleaned up the land right outside of the door and then added some stuff to the bench by the campfire workers.

Here's the .esp file if I don't end up doing this in the end.

EDIT: I claimed something else in the meantime.

Hmmmm. When doing interiors please don't touch the area outside the dungeon. It can cause conflicts with someone elses work. If you make a note about what you want outside that would be fitting, a landscaper might be able to help. 

Acknowledged.
