The Corpus surveyor Jena Xasparin says she found a solitary child, wearing this helmet, in the midst of a charnel field of remains. But they were the remains of Corpus troops. Some dismembered, some impaled... all burned. Nezha did it, the boy said calmly. He flew down from the sky and tore the enemy asunder with wheels of flame. When a child fell, he would raise them up again. Nezha moved quick as a scimitar, and the earth burned where his feet touched. Now the other had gone with Nezha, part of his celestial army. The boy had stayed behind to tell the story. To Xasparin, the boy was merely traumatized, the massacre probably a mutiny within the Corpus ranks. But Reshantur has been excavated, and every single one of the thousands of blackened bones that were gene-tagged... had belonged to an adult.
