Domains: Sacrifice, divine war, volcanic fire.
Era of ascension: Golden Age of Man (~150,000 years ago). Cohort: dead. Died: God War & Long Winter (~75,000 years ago), when a zealous follower deliberately triggered the eruption of Mount Kajiit to end the daemon wars, and the resulting volcanic winter killed Dyos's faith base along with all other Golden Age gods.
Worshipped by: Warrior-priest cults of the Golden Age. The orcish region now called Yugurbas Dyos — a contested marsh between Hedroscobb and Glivornax — preserves his name in the landscape, likely from an ancient orcish tradition venerating the site of the Long Winter's origin. No living culture worships Dyos. (The worships edge is authored downstream on the worshipper, not here.)
Overview
Dyos was one of the great war deities of the Golden Age of Man, governing sacrifice and the sanctification of divine conflict. His followers believed that blood given freely — whether of one's enemies or oneself — was the purest form of prayer. During the God War, this theology made Dyos's cult among the most aggressive of the warring divine factions.
The God War ended catastrophically when a follower of Dyos — acting from a combination of genuine faith and desperation — deliberately triggered the eruption of Mount Kajiit. The explosion was an act of sacrifice on a geological scale: the follower gave everything, including the world as it was, to stop the war. The resulting volcanic winter lasted millennia, killed millions across Alaria, and destroyed every Golden Age civilization including Dyos's own. Dyos died as his final worshippers perished in the cold and dark.
Legacy
The Long Winter that killed Dyos also ended the age of the great pantheon. Every Golden Age deity died in the same collapse. Dyos's name survived in the orcish landscape — "Yugurbas Dyos" — though whether the ancient orcs understood who Dyos was or simply inherited a name they found already carved into the land is unclear.
The eruption his follower set was the loud death; the quiet one had already begun. The anchor-vessel rite that seated Dyos on the material plane depended on Krathokh's priesthood, and when the God War broke those orders his binding attenuated like every other god's, the keystone gone well before the mountain opened.
