organic technology, just as the Shadows did, but he'd been able to find only the most vague information on it. Galen set his sensors to record.
Tentatively, he brought his hand to the wall, ready to pull away at the slightest hint of movement. The surface was hard yet warm, its yellow-green pattern shifting slightly. He detected carbon, silicon, oils, various organic compounds. Beneath the skin, electrical activity traveled along structures that resembled nerves, elastic fibers stretched like muscles, and liquid flowed through a circulatory system. When he'd been connected to Anna, he'd gotten a similar impression of the Shadow ships.
