Background
The chieftain of an Aztec tribe, he performed sacrficial rituals for his people.↗↗
Phantom Blood
Long before the events of Phantom Blood, the chieftain, wearing a Stone Mask, sacrifices a maiden on an altar as part of a ritual. His mask absorbs her blood and pierces his brain, turning him into a vampire. He proudly announces that he's gained eternal life, and then asks one of his followers to sacrifice his life-force; the follower obliges, and so the chief absorbs his blood. The rest of the tribe cheer for their leader.↗
It is unknown what happens afterward, as it is stated that this tribe disappeared from history, leaving only their ruins, never to be seen again. Nonetheless, the time of his tribe was the earliest known appearance of the Stone Mask.↗↗
