Detailed Walkthrough
The Erabenimsun Camp
If you haven't found out the location of the Erabenimsun Camp yet, return to the Urshilaku Camp and find out from the Ashlanders. The camp is located a little southwest of the village of Tel Fyr, south of Tel Aruhn. The quickest way would be to grab a boat to Tel Aruhn or a Guild Guide to Wolverine Hall (Sadrith Mora) and then head southwest to the camp.

Internal Disagreement
Speaking with either resident of the Ashkhan's yurt results in a brief response and a disposition drop when mentioning the Nerevarine or prophecies. Go and talk to the Wise Woman, Manirai, in her yurt. Make sure you ask her about Nerevarine prophecies. She explains that Ulath-Pal and his allies hate all outlanders and will never agree to call you Nerevarine. She suggests a simple course of action.

Kill Ulath-Pal and His Supporters
In order to be named Nerevarine of the Erabenimsun, you must first kill Ashkhan Ulath-Pal and his supporters, Ahaz, Ranabi, and Ashu-Ahhe. Ulath-Pal and Ahaz are both in Ulath-Pal's Yurt. They are the strongest of the four, and both cast spells. Ulath-Pal drops the War Axe of Airan Ammu and Ahaz drops Sanit-Kil's Heart of Fire. Ranabi is in his Yurt and should be defeated quickly to prevent him from casting spells. He drops the Robe of Erur-Dan the Wise. Ashu-Ahhe is next door in his Yurt, and deals a moderate amount of damage.

Persuading Gulakhan Han-Ammu
Visit Manirai after dealing with Ulath-Pal and his supporters to find out that Gulakhan Han-Ammu must be persuaded to name you Nerevarine of the Erabenimsun. She warns that it may be difficult to convince him. Go and speak with Han-Ammu. He explains that he doesn't want the title of Ashkhan because he lacks three basic attributes of a warrior: strength, courage and wisdom. To make up for his lack of attributes, he wants the magic items that belonged to his now deceased tribe members: the War Axe of Airan Ammu, Sanit-Kil's Heart of Fire, and the Robe of Erur-Dan the Wise.

Choose to offer him the magic items or show them to him. There are three possible outcomes: if his disposition and your Speechcraft are 50 or higher, show him an item and you'll convince him after some dialogue, if his disposition is 90 or higher and your Speechcraft is lower than 50, you'll have to give him all three items, but you get to keep the last one discussed (it is possible to place the desired item on the ground before speaking to him and then pick it up after handing over the other two items), or give him all three items.

Named as Nerevarine
With the magic items sorted out, Han-Ammu will accept his responsibilities as Ashkhan and name you Nerevarine of the Erabenimsun. Visit Manirai to receive the tribe's enchanted symbol, The Seizing of the Erabenimsun.

If all three Great Houses have pronounced you as Hortator and all four Ashlander Tribes have named you Nerevarine, head over to the Temple Canton in Vivec for the next part of the quest.

Notes
Ranabi also wears the Bitter Hand, Ember Hand, Bonedancer Gauntlet and Boneweave Gauntlet.
Ashu-Ahhe wears the Mountain Spirit cuirass.
Ahaz carries the Wind of Ahaz axe.
Tinti and Hairan from Marsus Tullius' Missing Hides Quest may become hostile after speaking with them, regardless of starting this quest or not. You will not be penalized if you kill these two.
