Iliath questline. Background on Iliath: Iliath used to be an Azuran shrine and an ebony mine (these facts may be related, seeing as how ebony = Lorkhan godsblood). The Temple later made it into an Ordinator training ground. Ashlanders and the Temple skirmished over the site off and on during the Interregnum, and the ebony mine was eventually exhausted around this time as well. By the current era, the place has fallen into disuse and since attracted a group of Sotha Sil priests who enjoy the solitude of the area.
Texture for Roth-Roryn that replaces the super detailed grass with the mushrooms (makes the texture look too busy, when Morrowind doesn't do that, clashes with the art style). This fits with the west gash textures that were left behind as well as blends in with the surrounding dirt and rock textures, and looks nice on cliffs.
Questgiver is someone of high ranking and/or a noble in Almas Thirr. Either can be a pre-existing NPC (preferrably one that isn't tied directly to a pre-existing quest) or can be an NPC created for this quest.
