Carl's Swirl Tattoo

Carl's Swirl Tattoo first surfaces as an enigmatic mark in the later arcs of the Dungeon Crawler Carl series, evolving from a subtle system anomaly into a symbol of deeper cosmic entanglement by book 8. Its presence hints at hidden layers of the dungeon's architecture and Carl's growing defiance against the AI overlords. Though details are sparse across the books, the tattoo underscores themes of transformation and resistance in the face of apocalyptic absurdity.
