I have released an update to Less Generic Nerevarine, to v1.3. For those who don't know, Less Generic NPC mods introduce unique dialog filtered for individual NPCs that replaces the generic responses usually encountered and create individual personalities and backstories.
Nerevarine gives such treatment to pretty much every NPC involved in the Morrowind Main Quest (MQ) that is not yet covered by an existing LGNPC mod (LGNPC PAX Redoran, LGNPC Tel Uvirith, etc.) This includes but is not limited to: Blades, Hlaalu Councilors, Telvanni Councilors, Main Quest quest givers/objects, Ashlander Ashkhans/Wise Woman, Temple Stewards, Dissident Priests, etc.
No changes to the Main Quest itself, although there are a couple of optional paths for side quests (I'm Not a Necromancer and Death of Ralen Hlaalo.)
Version 1.3 changes: Fixed a script bug, dialogue editing, added dialogue for a few overlooked minor NPCs involved in the Main Quest, and Master Neloth now is Skyrim: Dragonborn compatible.
