The Illuminated Tarot originated from Caitlin Keegan's interest in exploring tarot symbolism and archetypes. A card was randomly drawn each week, and a personalized version was crafted. By the conclusion of the year, a total of fifty-three cards were illustrated, combining the Major and Minor Arcana into a versatile deck suitable for both gameplay and tarot readings.

Within each set, there is a complete deck featuring illustrations and a booklet offering concise card descriptions and an introduction to card reading.
