Marduk had three moons; a big one, fifteen hundred miles in diameter, and two insignificant twenty-mile chunks of rock. The big one was fortified, and a couple of ships were in orbit around it. The _Nemesis_ was challenged as she emerged from her last hyperjump; both ships broke orbit and came out to meet her, and several more were detected lifting away from the planet.
Prince Bentrik took the communication screen, and immediately encountered difficulties. The commandant, even after the situation had been explained twice to him, couldn't understand. A Royal Navy fleet unit knocked out in a battle with Space Vikings was bad enough, but being rescued and brought to Marduk by another Space Viking simply didn't make sense. He then screened the Royal Palace at Malverton, on the planet; first he was icily polite to somebody several echelons below him in the peerage, and then respectfully polite to somebody he addressed as Prince Vandarvant. Finally, after some minutes' wait, a frail, white-haired man in a little black cap-of-maintenance appeared in the screen. Prince Bentrik instantly sprang to his feet. So did all the other Mardukans in the command room.
