The smell of crushed granite hung thick in the air.
In the underground testing range beneath Sub-Vault Four, Meng Shan stood planted like an iron obelisk, his black shield braced against a wooden target dummy that had been snapped in half like a dried twig.

He closed his eyes, setting the tin cup down on the stone.
