WHAT DOES THIS MOD DO?

Basically every official map, starting with the paper map shipped with the Morrowind Games of the Year edition up to the paper map shipped with The Elder Scrolls Anthology places the island of Solstheim roughly above Vvardenfell's north- western coast, with the southern tip slight above the southernmost Sheogorad islands.

This is a remarkable consistent location in a game series that regularly changes cities' names, disappears them or moves them around the map.
The only problem is that this is not where Solstheim is located in the game itself. It's too far to the west and south.
     
It becomes even more problematic as soon as the western landmass of Tamriel Rebuilt is considered - Solstheim almost blocks the harbor of    Baan Malur (Blacklight) and is a spitting distance from both Greenhold and Ystralond.
     
For an island that is considered a far-off backwater where legionnaries are sent as punishment, this is obviously nonsense.
     
Anthology Solstheim places the island where the maps up to the Anthology one agree it should be: 7 cells to the east, 6 cells to the north of its in-game position. In addition, the landscape changes of Bloodmoon Overhaul have been included (but not the meshes and textures as well as the changes to interior cells).

ISN'T IT TERRIBLY INCOMPATIBLE WITH EVERYTHING?

In a word: yes!
When modders tell you that they are making mods primarily for themselves, they are usually coqueting. I actually mean it.

Owing to the large-scale cell movement and internal Object Reference renumbering, Anthology Solstheim is basically incompatible with everything that touches Bloodmoon. If the mod in question is not in the list below, it is probably incompatible without patches/an edited version.
     
Compatible:

• Less Generic Bloodmoon, but it must load after Anthology Solstheim.
• Bloodmoon Rebalance is fully compatible and recommended.
  

Patches/Edits available:

• Tamriel Rebuilt Preview has a tiny landscaping issue in one single cell.
• The cell changes of Bloodmoon Overhaul are fully incoporated, but the fixed meshes and textures are only available in the Bloodmoon Overhaul archive.
• Wells Diversified's changes to the Nord wells have been incorporated and a version which only changes the Vvardenfell wells is available.
• Patch for Purists's script, floater, and placement changes have been incorporated as much as possible in the core files. A patch is available for statics and containers that PfP places into the world and would now float above the Sea of Ghosts.
• The Bare Necessities Water Sources makes both Skaal wells drinkable. A patch is avilable for the two new wells. Since it's an esp and one esp cannot delete objects of one, there are two floating wells and need to be removed by hand if they get in the way. [redo pending]
• The Neverhalls has a patch located in the Extras folder. Since the Neverhalls is an esp and one esp cannot override the files of another one, the objects added to cell -25/23 need to be removed by hand by editing The Neverhalls esp if they get in the way. [redo pending]
• Darknut's Greater Dwemer Ruins has a patch located in the Extras folder. It modifies the exact same cell as The Neverhalls, so the same issues apply. [redo pending]
• Vurt's Ground Cover has an edited esp in the patch folder, so you can generate grass as usual.
• The functionality of Fort Frostmoth Repaired has been added as an addon.
• Abot's Boats has a patch available for the scenic route to and from Fort Frostmoth and Raven Rock.
• Windows Glow Complete, although it is becoming outdated, nevertheless has a patch for the relevant settlements.
  

Third party patches:

• Something's Not Right... has versions for Anthology Solstheim and (the new) Tomb of the Snow Prince.
  
  

Confirmed/Currently Incompatible:

• Felsaad Revamped
• Frostmoth Docks Expanded
• Frostmoth Update
• New Hirstaang Forest
• Solstheim Castle
• Solstheim Lighthouse
• Solstheim Mages Tower
• The White Wolf of LoKKen
• Tomb of the Snow Prince
• ULS Solstheim    
  

Permanently incompatible due to lack of permission:

• Sea of Solstheim
