These "steam-parks" were never found in the game and the idea intrigued me. So, having the freedom as a modder, I decided to create my own take on what a steam-park would look like in Morrowind.
What you'll see in the videos is an old fortress which has been refurbished into a steam-park for natives and foreigners alike to visit. Yes, this is part of my Lyithdonea mod.
These two videos illustrate what I came up with. Enjoy!
