" No!” Kell shouted, reaching toward his brother, uselessly, desperately, but as his hand brushed the nearest person, the darkness leaped like fire from his fingers to the man’s chest. He shuddered, and then collapsed, crumbling to ash as his body struck the street stones. Before he hit the ground, the people on either side of him began to fall as well, death rippling in a wave through the crowd, silently consuming everyone. Beyond them, the buildings began to crumble too, and the bridges, and the palace, until Kell was standing alone in an empty world. And then in the silence, he heard a sound: not a sob, or a scream, but a laugh. And it took him a moment to recognize the voice.
It was his. "
