Continue after the main quest and you have to talk with vivic or you get to become a god or something like that. It's really hard to search for quest mods so any help is greatly appreciated.

Blades Quest: Prophecy of the Lost Heir: http://lovkullen.net/Emma/blade.htm
- A quest fit for the Nerevarine. Side quests and new companions too. You have to be the Nerevarine to play this mod

Vivec's Fate: The Ashlander Heresy: http://planetelderscrolls.gamespy.com/View.php?id=4590&view=Mods.Detail
Synopsis:
This plug-in tells the story of what happens after you complete the main quest in Morrowind - the resurgence of the Dissident Priests, and the crisis in the Temple.

As events unfold around you, you must decide how to relate to them.

You can play as an Ordinator, Ashlander hero, or find your own way.

Thanks.

A Call to Issilar:
- travel to a distant island inhabited by Argonians and dominated by a massive volcano.

Nerevarine's Castle gives you a castle with lots of stuff, lots of rooms, a very useful teleport network, a nearby town, and a quest to open up the mines underneath.

here's one, http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=5472, i have not played it though i might try one day. as it conflicts with almost every other landmass adding mod out there.

i have that mod (though i've never played it due to a bad modding frenzy) but after reading that i ran it through tesfaith and it didn't even seem to conflict with anything, it made a big square in a far away place, and edited some of morrowinds cells for it's story

oh, ok i thought that one was the one that put five or six large islands almost entirely encircling the island. do you remember which one did that. i think it had a similar name.
