Orion strode back into the hall, his expression clouded with concern as he surveyed the depleted containers that once brimmed with dark blood. The mysterious runes etched into the floor seemed to hum with latent energy, their purpose still shrouded in enigma.

He pondered the possibilities, each scenario more perplexing than the last, but the answer remained elusive. For now, he pushed aside the puzzle, focusing instead on the immediate task at hand.
