Good idea (although... you're not the first to do it...
, but I don't see why it's necessary to have 6 cells. The interior I linked to uses one cell for the labyrinth part and creates additional confusion by covering everything with a huge plane of blacksquares. That should serve as a major source of inspiration for you. If I finish my ShotN claim soon enough, you may want to take a look at that too, since it's going to be fairly similar.
Yes, I'd like to check out yours. What claim is it?
Are we allowed to cover the entire cell with black squares? I've thought about doing that but I know there are people who would bitch and complain that the minimap is rendered useless. Sometimes it won't help any ways because my cave designs are more vertical than horizontal, so using the minimap doesn't really help.
I like Andres Indoril's idea. I was doing something like that a long time ago for a showcase for SHOTN, which wound up being just an experimental wip. The ideas I had for that are ideas I want to use for the Labyrinthian for SHotN. I've never liked TESV's interpretation of it, ever. I'll post my labyrinth wip on SHOTN in a little bit just for ideas.
The vision I have for Smoke Hole Cave is one door leads to a small cell, which has a few other doors, and one of those doors leads to another cell with other doors, etc... until you finally get to the Sloads' lair. I won't make it too ridiculous but the purpose of having tons of different cells is obviously to mislead the player. Some will lead to treasure, some will lead to nothing, some will lead you in circles, and one will lead you to the Sload. Since the Sload are very magical, especially in mysticism, I want to make a couple areas, or maybe the Sload lair, require mark and recall. There's a trick I've been wanting to use with the wall pieces for a while now. You know how they are transparent on one side. I'm thinking of a hallway where you can see the exit at the end which leads to the lair, and when you get into the lair, if you turn back around, you'll see there is a wall right where you just came out of. It's putting a wall in front of the cave entrance basically. This is done magically by the Sload, who know other forms of magic that most Tamrielians do not. I would put some kind of warning like tons of corpses in plain sight and a note or something on the ground that warns the player to "be skilled in teleportation like the Sload, for there is no escaping these depths." or something like that.
