Like tears... in... rain.
It is a land of deep jungles and golden seas, mysterious and unexplored.
It is a land of knife-edged mountains and deadly glaciers, trackless and forbidding.
You live in an age when humankind is a young race, newly arisen on an ancient and monster-haunted Earth. Mighty cities and sprawling empires rise and fall, weaving tales of great deeds and epic tragedies that will be lost and forgotten by the peoples who come later. Even the land itself is fated to fall beneath the numbing cloak of endless winter, burying the triumphs and defeats of this vanished age beneath miles of ice.
All those moments will be lost in time, like tears…in…rain.
But for this glittering moment in the slow dream of time, Thule lives — and it is a fierce, cruel, splendid, and marvellous moment indeed!
This is a Dungeons & Dragons 5th edition game, set in the Primeval Thule campaign world.
