"Given their bloody history, I cannot imagine anyone venturing into the southern jungles looking for the Opaya. Nor can I imagine the madman who could confront the Opayan deathseers and walk out of Torajan with one of their hoods."— Abd al-Hazir(src)
The Opaya are/were a tribe of humans who live(d) in the southern Torajan Jungles. They have a bloody history, and employ deathseers. Much to the surprise of Abd al-Hazir, one individual did emerge from the jungle with one of said deathseers' hoods.
