The catacombs, once a looming maze of uncertainties, began to undergo a subtle transformation after the challenges presented by the Keeper were met. A sense of calm reverence permeated the air, casting away the heavy atmosphere of foreboding. Gone were the cold and unwelcoming shadows; in their place, a soft, golden luminescence emanated from the walls and ceiling. It felt as though the very heart of the catacombs, perhaps even the spirits of old, were acknowledging their success, enveloping them in a comforting embrace.
