Westerlings (Earth-63)

The Westerlings were Humans who lived in Darmos, the continent West of Ajia, and were enemies of the Free Peoples of the East.

The Westerlings were a significant threat to Konohagakure; they were a more regimented force than the Ōku or even the Kaizoku. Kaguya drew much of her inspiration for her Ōku armies from these wicked Humans. Kaguya suffered a harsh and heavy defeat from the Last Alliance, who vanquished her numerically superior Ōku with a ranked and ordered army. The Westerlings were all this and more, so Kaguya greatly valued her alliance with the Humans of Darmos.

History
In the First Recordation, Humans awoke in Dartock in the West. Some of them were early corrupted by Zetsu, prompting others (the Yoidansei) to migrate eastwards.

Centuries later, after Doragonbōn, tribes of Humans joined the Yoidansei in Beruyo, long after their arrival. These Humans came from the west, and were also called "Westerlings". Two of their leaders were Emon and Ultgang.
