The Spire of a Hundred Veils is a legendary tower labyrinth that pierces the sky, said to contain one hundred floors of shifting chambers, ancient guardians, and impossible architecture. For centuries, it has been sealed, but now its doors have opened, and something within has begun to stir. Strange omens ripple across the land: birds fly in spirals, mirrors show rooms that do not exist, and sleepers dream of climbing endless stairs.
The adventurers are drawn to the tower by visions, promises, or duty, and must enter its lower floors to discover why the Spire has awakened. What begins as an expedition into a mysterious ruin soon reveals a deeper threat: the tower is not merely a dungeon, but a prison, and its warden has been corrupted by the very power he was meant to contain. The first act takes place in the tower's foundation levels, where the party must secure a foothold, uncover the first clues about the Spire's true purpose, and learn that a far greater evil waits at the top.
