You followed Muirchertach deeper into the heart of the stone circle, feeling the ancient magic pulse around you. As you tread upon the sacred ground, a faint glow emanates from the stones, illuminating your path with an otherworldly light. You sense a shift in the air as Muirchertach leads you to a hidden chamber where a pool of shimmering water reflects the starlit sky above. The ethereal being gestures towards the pool, hinting at the truths it holds within its depths.
