Glass
Glass can neither be shaped nor destroyed. It cannot even be touched, for any contact with Glass turns all living things into Glass. Yet Glass has a source—a mysterious place in the north from which it slowly spreads, engulfing ever larger territories.
Thirteen people—failures, outcasts, criminals, and adventurers—set out toward the source across a frozen wasteland, each carrying their own burden, their own story. As their paths intersect, these stories intertwine into a strange and intricate web, spanning dozens of lives, cities, generations, and eras. At the head of the expedition stands the enigmatic Guide—perhaps a Messiah, perhaps a cunning impostor, or perhaps both at once.
