Domains: Kingship, law, civil order.
Era of ascension: Golden Age of Man (~145,000 years ago). Cohort: dead. Died: God War & Long Winter (~75,000 years ago), when every Golden Age kingdom collapsed and the concept of legitimate kingship he embodied ceased to have practitioners.
Worshipped by: The royal courts and legal institutions of the Golden Age civilizations — those who ruled, judged, and maintained civic order. No living culture maintains his worship. (The worships edge is authored downstream on the worshipper, not here.)
Romath was the theological justification for kingship in the Golden Age: a king ruled because Romath sanctioned it, and a king who lost Romath's favor lost his legitimacy. The God War fractured this framework as rival kings claimed divine sanction for fighting each other; by the time the Long Winter ended the debate, every king was dead and Romath with them.
Kingship outlived him only briefly; the rite outlived him not at all. Romath's presence on the material plane was held by the anchor-vessel rite that Krathokh's priesthood performed, and once the God War broke those orders his binding attenuated no matter how many kings still claimed his sanction.
