After the loud sound of the cannon faded, it was quiet except for a ringing sound. A big cloud of hot dust and ash floated out from the fortress, smelling like burnt metal. In the place where the solid black wall was, there was now a giant, gaping hole, and its edges were glowing and melting.
The team picked themselves up, their ears still buzzing from the blast. Draven stared at the opening, his mouth slightly opened in disbelief. "Well," he finally managed to say. "You certainly know how to knock."
Seraph was already on her feet, her expression all business. "The hole won't stay open forever! Let's go!"
Jonah felt dizzy. Summoning Atlas, even for a short time, had used more of his energy than he thought it would. He took a deep breath, focusing his mind. In his head, he gave his giant creature one last order. Rest.
