Tamriel Rebuilt (also known by the abbreviation 'TR3') is the largest collaborative fan-based modding project for the Elder Scrolls series. This project has existed since before Morrowind's release, though the leadership and members have changed many times since then. They are currently creating the province of Morrowind on Morrowind's engine.
Tamriel Rebuilt is a group collaboration, a project which has involved over 200 modders and contributors over the years. Tamriel Rebuilt was founded in 2002 by a gaming enthusiast under the alias 'Ender', before Morrowind was even released. Sacred East, as well as updates, bug fixes and new quests for Telvannis and Antediluvian Secrets, was released on 6 June 2012.
 Organization Process
Tamriel Rebuilt progresses 'in stages', a term which essentially translates that one area of modding must be completed before work can begin on another. The order of progression typically starts off with worldspace work, with exteriors constructed to cater for interior design. Once the worldspace has been created, inhabitants including both NPCs and Creatures are included, and then accompanying dialogue, and later quests.
Files for Tamriel Rebuilt are organized into individual 'claims'. The claims are managed in different departments, encompassing all the aspects of the mod. The departments are divided into those of Exteriors, Interiors, Quests, Objects, and Sound, who handle their respective area. The departments are under direction of one user, a 'Head of Department', who supervises the conception and direction of the claims. Once a claim has been fulfilled, it undergoes a vigorous 'Reviewing' process. Designated users thoroughly examine every aspect and detail added by the claim, deciding if it fits the impeccable criteria required to be merged into the mod and eventually released to the public. Moderators and Administrators must then confirm the claim, although if the standard is not adequate the claim can be rejected and subjected to a reconstruction.
Tamriel Rebuilt's forums are also divided and the visibility and access is restricted to certain members of the project. Guests and Members can view most sub-forums, while Tamriel Rebuilt Modders can also view additional subforums for internal releases and design for the mod. Reviewers can also see hidden sub-forums for reviewing purposes.
 Morrowind Maps
Prior to 2010, Tamriel Rebuilt was billed to divide the mainland of Morrowind into six distinct maps, all of which were to be developed separately and sequentially. Due to a re-organization in 2009, the number of six was increased to eight, to increase productivity and general public accessibility.
Although the division between the maps are mostly arbitrary, regions correspond loosely to the areas governed by different Great Houses. Current Maps that are released to the public include Map 1 ('Telvannis'), Map 2 ('Antediluvian Secrets'), and Map 3 ('Sacred East'). Both Telvannis and Antediluvian Secrets cover the regions ruled by the House Telvanni while Sacred East is centered around cities of House Indoril and the city of Necrom. As for the rest of the Maps, Map 4 contains the rest of Indoril's holdings including the capital city of Morrowind, Mournhold, Map 5 covers "a bit of every sort of region Morrowind has to offer", including both Imperial and Hlaalu cities, and Map 6 will contain House Redoran holdings in the Véloth Mountains. The final Maps to be released are scheduled to be Map 7, which is centered around the city of Narsis, capital of House Hlaalu, and Map 8 is set to finish the series by concentrating on the stronghold and setting of House Dres.
