Edit: Forgot to add a script to the doors.
Here’s my submission for Questing + Scripting.
Go to the center of Seyda Neen to find a mysterious potion. Drinking it will send you to a location that looks strangely similar to the plaza in the St. Olms canton, but devoid of everything except for a Dremora and a number of chests. Talk to the Dremora to learn more about his game…
Note: I used “MenuTest 0” to close the inventory screen immediately after the player drinks the potion; this can sometimes cause a crash. If it weren’t a consumable object then I’d use a less crash-prone command.
Interior cell added: “TexShowcase”
New items/scripts are prefaced with aTex_
Requires Tribunal for a certain script command
