I believe I've seen the Form Tamriel decision, but what makes that specific option available?

Vampire culture group or Cyrodilic culture group. But not Nedic.

Alright cool, thank you!

Any recommended dlc?

Dharma

When turning into the Alessian Empire, how do I change my religion to the Eight Divines? I've had the events appear saying that the Eight Divines are here and are converting my provinces but I've no option to actually change to their religion.

There actually should be an event for that...

In what date are you playing?

281. The events of the EIght Divine conversions started around 250 or something but they've seemed to have just stopped now.

I think Alessian Revilt is text chapter, there you should be able to convert to eight divines via event. If not, type me, maybe I will need to improve the code.

im trying to install this mod however it only installs the.zip and not the.mod

Then you need to try direct download. There are both .mod and .zip files.

Maybe making the Tribunal the actual rulers of Morrowind and giving that nation pops that reflect the Tribunals strength.

Well, I think I can replace Morrowind with Tribunal in one of the next bookmarks, as we also need to put clerics in power in some Dunmer Houses. But I cannot promise anything about Pops, because they are already used in Chimer Pantheon and I have not tested game with multiple pops yet.

Can you make a stand-alone music mod? It's wonderful!
