So with all the crazyness in this world right now, I've had some time to check out Morroblivion again, and the work still being done on it is awesome! I kind of stopped modding a few years ago due to work and time constraints, but now I decided to check out my old modding files again.
What I found were two mods I had converted and practically completed debugging and even had added some extras.
I playtested them the past few days and they can be completed and don't really seem to have any bugs, though I made a few adjustments.
I won't really have time maintaining them longterm, but I decided to release them to the community anyways, as they seem to work so well. However any bugs found in the next week or so, I can probably fix.
The first one is Tel Nechim by Antiscamp. You can check out pics and the description at its Nexus Page.
There's also a nice showacase on Youtube
I left it in the Morroblivion worldspace and added new textures for the ingame books and some of the NPCs have schedules. To go there, simply talk to the ferryman in Sadrith Mora.
All credits go to Antiscamp who did a wonderful job at creating these islands and quests.

Excellent job! The more
Excellent job! The more content for Morroblivion the better, and the mod looks good.
So I assume this is based on the original version which conflicts with Tamriel Rebuilt. I don't think too many people would be using the converted Tamriel Rebuilt anyway because based on the tutorial here:
https://morroblivion.com/forums/morroblivion-development/tutorial-converting-tamriel-rebuilt-to-morroblivion
It looks like a very involved process and a lot of troubleshooting to get working, also there appears to be a lot of bugs even after conversion so not to many people would be using the converted Tamriel Rebuilt, so shouldn't be a problem.
Did you use a similar process to convert Tel Nechim for Morroblivion but doing the unique debugging appropriate for this mod.
