Folks have been working on Tamriel Rebuilt for nearly 20 years now. I think preliminary work started as soon as Bethesda announced the game would be limited to the island of Vvardenfell. The project did go through some doldrums in the mid-'10s, but was reinvigorated once it set up a Discord server and brought in some new talent.

Tamriel Rebuilt/Project Tamriel Map

The lighter areas on the map (Morrowind, the Reach, and the Island of Stirk) are the places you can actually visit as a player (though I should caution that southern Morrowind is basically a big flat expanse of nothing right now). There are also plans to do work on Yokuda and the Padomaic Isles.

Thanks for the welcome!

First off let me say it is good to see you here, WellTemperedClavier.

Tamriel Rebuilt is one of the best land mass mods I've had the pleasure of experiencing. Much has been added to it since I last played with it in 2017. If you just like to walk around exploring then another good land mod is Melchior Dahrk's Lyithdonea - The Azurian Isles ALPHA. Very much unfinished but beautiful to view.

Funny you mention that, we were just talking about Lyithdonea on the TR or PT server. I was thinking I might download that and take a look around. The screenshots are fantastic.

Also, I like the Planescape: Torment reference in your signature!

This mod just came out and seems pretty interesting.

Basically, it lets you create books and sell them in-game.
