The decrepit old man hovered in the air for a moment, suspended above the vast expanse of the massive hall. Slowly, he opened his mouth and took a deep breath that resonated with an otherworldly force. As he inhaled, all the wild and chaotic energy within the hall began to swirl and converge, drawn inexorably into his body like a vortex consuming everything in its path.
This initial intake was just the beginning. The devouring power emanating from the old man grew exponentially stronger with each passing second. The very air trembled as more and more energy flooded into him. His presence became a black hole of sorts, pulling in not just the ambient energies but reaching far beyond the confines of the hall.
