Flayed Twins

The Flayed Twins, also known as the Flayed Ones, or simply The Flayers, are a pair of gods who demand huge amounts of sacrificial blood to live. , without which they would descend and drain the blood from all the peoples of the Xhacatocatl mountains. The Flayed Twins cannot be destroyed or banished to another realm.

The blood of the Twins themselves are used in staining fabrics and quenching weapons, although how their blood is obtained is uncertain.

Minions
To prevent the depopulation of their lands, the high priests of the plateaus must satisfy the Flayed Twins' lust by sending out the likes of Strygwyr, who engages into an unending hunt for more victims to use in ceremonial sacrifices, transferring their blood to the Flayed Twins through sacred markings on his garb. It is said that, in his frenzied bloodrage, the Flayed Twins sometimes takes control of Strygwyr, projecting their own appearance into their hound. Strygwyr wears a hood which covers his eyes, as the Flayed Twins guide his movement through their sight.

Bonehunters perform a similar function in the drylands west of Xhacatocatl, where they hunt a variety of beasts.

The Flayed Ones also employ a gigantic bird of prey called Iczoxtotec, who soars the skies in search of battle, and therefore fresh victims for sacrifice. Ravens are common above the sacrificial altars, and their inhuman lust for flesh has made them a sacred symbol of the Flayed Twins.

Rivalries
According to Strygwyr, the Flayed Twins demand the sacrifice of the Omniscience, a rival god.

Strygwyr is also close to the demon Eztzhok, wielding their blades in his hunt. This is met by disapproval from the Flayed Twins.
