Serrin was awakened by the conductor as the express pulled out of Koblenz. His arm throbbed and his mouth felt like a parakeet had been living in it, but his heartbeat seemed normal and the only other lingering symptom of the attack was a tight, knotted stiffness in the muscles of his arms and legs. While fumbling in his pockets for the ticket, Serrin’s hand rattled something metal and he hurriedly coughed to cover up the sound. Once the conductor finished looking at the ticket as if it were something he’d been unlucky enough to step in, the elf waited for the man to move on up the aisle before pulling the metal object from his pocket. It was a cartridge, the kind used for medical injections. Empty now.
