The founding cataclysm
The Fall.
A cold, devouring dark — the Gloom — came over the world, and in one cataclysm the light fell and a city fell. That is the critfall: the event the whole universe is named for.
Above, the Gloom snuffed civilization and left only embers of a light that had once been everywhere — the Founts ofEmberlight, a frontier fighting to rekindle the fallen light hearth by hearth. Below, a great city fell physicallyinto the earth and never climbed out; cut off from the sun, it answered the same cold with a colder light — the ledger ofGrimecrawl, where debt is the only warmth.
Fire above, ledger below — two lights against one dark.
The long age after the Fall — when the fires had gone out and could not be relit — is the Unkindling. It has receded, not ended: the Gloom still holds the dark places, and still surges. To hold light in Vharendol is not to have won, but to be currently winning.
