Clash on the Twin Peaks

Farther back, the Abyssal demon frowned as he noticed the growing number of demons bottlenecked ahead. From his vantage point, he couldn't see the soldiers holding them back—only the mass of his horde piling into the narrow crossing. His frustration mounted as the bulk of his army slowed to a crawl. 

"What is happening up there?" The Abyssal growled, his patience wearing thin.

Just as the demonic mass in the bottleneck swelled to over forty thousand, a blinding flash of light erupted from the ground beneath them. For a brief moment, everything seemed to freeze. Then, in the next instant, a massive explosion of lightning and fire ripped through the horde with cataclysmic force.

"BOOOOOOOOOOOM!"

The blast was like a storm unleashed from the heavens, a swirling vortex of fire and lightning that tore through the demons with devastating ferocity. The ground shook violently as the explosion expanded outward, destroying everything in its path.
