As the Olo'eyktan of the Omatikaya, Eytukan was the clan's warrior chieftain and husband to the Tsahìk, Mo'at. He sought game to feed his people, oversaw the training of young warriors and hunters, and safeguarded the clan from external threats. He was stoic and calm by nature, but also a fierce provider and protector.
Eytukan learned to put his conflict with the Sky People aside during his interactions with Jake Sully, accepting him as a member of the Omatikaya clan. His leadership of the clan would eventually be passed on to Jake after the events following his heroic death in the destruction of Hometree.
Eytukan may be dead, but, like all Na’vi, his “memory” resides in the network of Pandora and is accessible via the Utraya Mokri (Tree of Voices). This is where Jake seeks Eytukan’s guidance for how to lead the Omatikaya during challenging times.
