Arakaul "the Unbroken" was an Orsimer who served with Baloth Bloodtusk during the Siege of Orsinium. In The Elder Scrolls Online: Orsinium, he is not interacted with, but when you drink from the water in Honor's Rest, you are transported in his body to a memory of his.
Early in his life, Arakaul killed the chief his clan but decided to leave. He was shunned by both men and elves, later joining the Savage Sons. Arakaul fought alongside Baloth Bloodtusk, not for money, nation, or royalty, but for his brotherhood. He spoke to Baloth about the Sons' involvement in defending Orsinium during the siege, prior to him agreeing to King Joile's duel. Arakaul later died fighting in the later years of the Siege of Orsinium, with his urn being buried in Honor's Rest.
When entering Arakaul's crypt in Honor's Rest, you are transported to his memory after drinking the water beneath his burial urn. In the memory, you relive Arakaul's interactions with Baloth Bloodtusk and Commander Reliana prior to Baloth and Gaiden Shinji's duel. Once this is finished, you are transported out of the memory.
