Way of the Tattooed Temple

Some monks treat their bodies as temples and adorn them with vivid art honoring their values. Practitioners of the Way of the Tattooed Temple ink their bodies as they reach milestones in their personal journey, infusing some of these tattoos with mystical energy that evokes magical properties from the ink. Although some look askance at the appearance of these monks, none doubt their supernatural power.
