Detailed Walkthrough
While walking the southwest of Coldharbour, you may come across Treeminder Xohaneel, asking you to help her people of Haj Uxith settle a great debate between their scholars and warriors. However, she won't go into detail before you have proven your worth to each faction by completing the trials of the spirit and body.

Trial of Spirit
Speak to Treeminder Xohaneel to start the Trial of Spirit.
When doing the Trial of Spirit, you must talk to three individuals and give them each an amulet that represents the quality they show in what they do. there are three amulets: Courage, Endurance, and Preservation.

Give the Amulet of Courage to Teelawei for negotiation between the two factions and the people of Coldharbour.
Give the Amulet of Endurance to Desh-Wazei for gathering food to help her people.
Give the Amulet of Preservation to Ashgar for maintaining the traditions and customs of their people.

After you have given away the amulets and receive a gem for each trait, run up to the top of the xanmeer to find three statues: Life, Time, and the Unknown.

Place the Gem of Courage on the Statue of the Unknown.
Place the Gem of Endurance on the Statue of Life.
Place the Gem of Preservation on the Statue of Time.

Once you have placed all of the Gems, you need to run back down to the first level of the xanmeer to talk with Xohaneel. Tell her you have successfully completed the Trial of Spirit

Trial of Body
Sabotage the Sap Collection Facility|thumb|right
Speak to An-Jeen-Sakka to start the Trial of Body.
To  complete the Trial of Body you must enter a trapdoor at the top of the northern xanmeer before passing through several rooms containing Argonian peasants before entering the Daedric Sap Collection Facility. You then need to collect some treated wood and then add some to each of the six marked fires under the vats, which will melt the metal vats that are used to boil the Hist Tree wood. 

There is an alternative exit on the west side of the room, which exits outside opposite the wayshrine. Return to An-Jeen-Sakka to complete this trial.

Settling the Dispute

Once both trials have been complete you need to speak again to Treeminder Xohaneel, who will inform you of the details of the two factions dividing their community. The warriors lead by An-Jeen-Sakka wish to keep the Hist alive although in eternal torment by Molag Bal. The scholars led by the treeminder believe the Hist should be allowed to die ending its torment.  If you side with the scholars, you will have to convince An-Jeen-Sakka to accept your decision either by defeating their champion or by intimidating him. Alternatively, if you side with the warriors, to will have to convince Treeminder Xohaneel to accept your decision either by defeating their champion or by persuading her. If you side with the scholars, you must then destroy the vampiric shard by the Hist Tree. Finally speak again to Treeminder Xohaneel/An-Jeen-Sakka to complete the quest.
