As I mentioned in the Morrowind mods thread, I updated to Morroblivion 0.65. It does have an optional .esp to add a transport between Morrowind and Cyrodiil. It puts an NPC on the ship you arrive on at Seyda Neen, who you can talk to to go back to Cyrodiil. That puts you at the Imperial City Market District Gate. There is a Khajiit standing there at the gate who will likewise transport you back to Cyrodiil. It seems a little odd that that you would show up there. The IC Docks would have made more sense, I think. But it does work.
That is also part of a Chargen mod. I am not sure what the character generation part of that does just yet. Ok, I experimented with that, and the character generation part of it is not working for me at all. The mod is supposed to start you with an empty cell and give you the option to start the game in Cyrodiil or Morrowind, with added options of doing each the vanilla way, or a faster way. But it just does the regular Morrowind start for me every time for me.
I also found an improved map mod today.
New HD Map is in 4k, and perhaps best of all, the locations seem to all line up correctly.
Edit: Well, I gave up on version 0.65. The Distant LOD land was not appearing! The distant trees were there, but no actual land. After spending about an hour fighting with it, I just removed it and reinstalled version 0.64. Now I have distant land again!
