Imperial Mysteries
A supplement for Mage: The Awakening that expands the game to archmaster-level play. It provides rules for the sixth through ninth dots of the Arcana, details the Threshold and its trials, and explores Ascension, the Supernal Realms, and the transformation of the Fallen World. The book describes rival visions in the Ascension War, the alliances and strange realms surrounding archmages, and the godlike entities they encounter. It also includes a minigame set in the Supernal and Storyteller guidance for chronicles on a cosmic scale.
