Coriantumr (last Jaredite king)

In an effort to preserve his kingship, he wages war with the men who desire his sovereign position, including Shiz.

The two men participate in a great last battle with their armies at the Hill Ramah, where Coriantumr decapitates his enemy.

With the armies annihilated and only two Jaredites left alive, himself included, Coriantumr wanders through the land and is discovered by the people of Zarahemla, who are a remnant of the Mulekites.

Ether tells him that the Lord will spare him and his household if they repent; otherwise, they will be destroyed and another people will inherit the land; further, Coriantumr will be the last survivor to see them do so.

Gilead and his army are beaten and chased to the wilderness of Akish, with thousands of people getting murdered along the way.

Gilead rushes to the Land of Moron in the night while Coriantumr's army is drunk, killing several people.

[10] The stench of the dead bodies is so strong it disturbs the people, but Shiz continues his ravaging, swearing to avenge his brother.

[5] The two leaders fight until Shiz faints due to blood loss, after which Coriantumr cuts his head off.

[22]:181 Charles W. Dunn depicts Coriantumr's last battle—which ended Jaredite society—in his book The Master's Other Sheep: An Epic of America and Other Poems.
