Percy Jackson realized the gravity of the situation as he saw a giant fall, prompting him to yell an urgent command that was drowned out by the wind. In a decisive move, he plunged his sword, Riptide, into the ice beneath him, causing a massive tremor through the glacier. This disturbance affected the ghosts around him, bringing them to their knees as a powerful wave surged ominously from the bay, even taller than the glacier itself.

The relentless wave unleashed water from various cracks in the ice, resulting in chaos as it struck the camp. Buildings crumbled, and the glacier's edge began to break apart, plunging everything—including Percy and the ghosts—into the abyss. The intense scene highlighted the precariousness of their situation, combining elements of danger and urgency in Percy's quest.
