Oguanabara

Oguanabara is a jungle peninsula forming the northern edge of the Acua Gulf in the East District. Gulf waters surround it on three sides, with the wild lands of Awok and Aricagua to the north. Its only inhabitants are a small tribe, the Abara, tall and dark-skinned and thought to be related to the Nazca. They are greatly feared for their hostility and grisly customs; the people of Awok count them dangerous, degenerate cannibal cultists.

Chief among these customs is head-hunting. Abara warriors range widely, hunting for food and for people of other tribes, and kill any human they meet. The victim's skull is removed, the eyes and lips are sewn shut so the spirit cannot come back, and the remains are treated with herbs and packed with hot sand, which preserves and shrinks the head. Warriors hang the heads by the hair and wear them as proof of skill in battle, and a warrior of either sex gains standing with every trophy.

Traders nonetheless seek these heads, which sell for 1,000-4,000 G.P. as curios in some lands and as fetishes among necromancers and other black magicians. The Abara reportedly will not kill Andaman, whom they think akin to demons, so some Andaman tribes trade them live human captives for heads, reputedly at two or more people per head, which may explain how such trophies reach places as far off as Tartessos, Qaddan and Sheba.
