The coupling door slammed shut behind them with a rattle of metal. Wind roared through the narrow gap between cars, howling in Lucen's ears as he steadied himself on the grated floor. The freight car loomed ahead, its rusted panels groaning under the strain of something crawling along its roof.
From here, Lucen could see it properly: the bulging dents moving steadily forward, each one accompanied by the sharp screech of claws digging into steel. Whatever was up there was big enough to shift the train's balance.
Varik tilted his head back, watching the roof bow under another clawed step. "It's heading for the engine."
Lucen smirked faintly, mana already simmering beneath his skin. "Guess we'd better stop it before it pulls the brakes for us."
The bowman stumbled out behind them, pale-faced and gripping his weapon like a lifeline. "What the hell is that thing?"
Lucen didn't bother answering.
