The Age of Lumen (abbreviated AL) is a dating system used principally in the city of Lumen on the continent of Addar.
The system marks the passage of years since the founding of the religious order known as the Aspirants of Lumen nearly 2,360 years ago. The year of this event is year 1 in the Age of Lumen, and is equivalent to 1160 BA in the more common Years of Anharos.
