Chapter 924 - Vex was kidnapped.

The afternoon in Asgard remained cold, but alive, when Strax and Vex left the railway station to cross one of the nearby commercial avenues. The outing had lasted longer than he had planned, partly because Vex had stopped in front of every detail of the train as if she were facing a discovery capable of changing the very structure of the world. She did not merely want to know how it worked; she wanted to understand why it worked, who had built it, how many wheels it had, why it released steam, whether it could become faster, whether it might fly someday, and, most importantly, whether anyone had ever tried talking to it to check if it was perhaps a living creature disguised as a machine.
