The bone fence shattered. It was impossible. Harrow now clearly remembered the wall of bone she had summoned up around herself, Gideon, and Camilla Hect, in those dreadful final moments on the garden terrace. She had been almost spent, and yet her barrier had held off a determined onslaught by one of the Emperor’s fists and gestures for at least a minute. Cytherea had been ten thousand years old and heir to limitless necromantic power. The Sleeper had a baggy orange suit and a gun collection.

The bone barely even seemed to break; it simply flaked away in chunks, like old plaster from a ceiling.
