RATH & Man-made underground passage in Carnlea

Under Carnlea, a man-made passage cuts through ancient earth, joining a rath to the hidden world below. Built in the early Christian period, it served as a secret route for residents who needed to move unseen when danger gathered outside. The darkness inside would have swallowed torchlight and echoed every footstep, turning a simple journey into a test of nerve. Perhaps families used it during raids, or perhaps priests carried sacred objects through the black without witness. Either way, the passage remains a deliberate wound in the land, proof that people shaped Carnlea to hide as much as they revealed.
