Domains: Trade, roads, the rebuilt routes.
Era of ascension: Age of Craggus (~42,000 years ago). Cohort: dead. Died: Lost Ages (~30,000 years ago), when the Laughing Plague made travel synonymous with carrying death and the road-emptying that followed extinguished the cult almost overnight.
Worshipped by: The merchant guilds of the Craggus era, the road-builders who cut the post-Winter routes through landscapes still half-thawed, and the route-watchers stationed at the small relay-hostels that the long trades depended on. No living culture maintains his worship. (The worships edge is authored downstream on the worshipper, not here.)
Tylloréth was movement-of-goods-between-places. Tyvak had the production — the forge, the labor, the iron — and Tylloréth was the next stage: what the labor produced had to go somewhere, and the journey itself had a god. The merchant prayer was three lines, said before the cart pulled out, and held the asking of safe road, fair price at the far end, and the route's continued openness. His priesthoods were embedded in the guilds — they were also accountants, route-planners, and dispute mediators when carts of different houses met on narrow roads. The cult's records are mostly ledgers.
The Plague killed him by inverting the prayer. A merchant on a route was now, statistically, a carrier; the safe-arrival the prayer asked for was the next town's catastrophe. Trade collapsed within a generation as polities understood what the carts were bringing them, and the guilds dissolved before the Plague had reached most of their members directly. His priests went with the guilds; the relay-hostels emptied; the routes filled with grass. The roads themselves survived the cult by tens of thousands of years and are still in places visible in modern terrain, which Erindath's school treats as one of the legible material legacies of the Craggus era — though Erindath's school does not name Tylloréth.
