Only two helmeted figures remained on the ladder below him; Tarquinia was already inside. The craft’s interior had been kept pressurised for the sake of Azelio’s seedlings, so it was necessary for each of them to wait their turn to cycle through the Surveyor’s small airlock. As Azelio opened the hatch, Ramiro pictured himself releasing his hold on the ladder, starting up his jetpack and fleeing across the slopes. If he hadn’t left it so late he might have thought up a way to fake his own death out here. There were probably a few antimessagers still walking free who would have been willing to shelter him.

Agata entered the airlock. Ramiro’s pride had the better of him now: he wasn’t going to hand a moral victory to any ancestor-worshipping messager. He started down the ladder slowly, timing his steps so that he wouldn’t arrive too soon.

When he reached the hull he could see Tarquinia clearly through the front window, already busy at the navigator’s console. A moment later the first warning light blinked out on the panel beside the airlock: the inner door was closed. He waited for the pressure to be pumped down; with a finite amount of sunstone to gasify, they weren’t going to throw away any more air than was necessary.

The second warning light went out. Ramiro gripped the crank with his feet and began turning it. Once he passed through this hatch, he’d have nowhere to escape to for the next six years. But he’d been forced here by his own nature, as much as by his circumstances; he wasn’t merely exchanging one prison for another. And once he’d passed through these temporary constrictions, there’d be infinitely more elbow room in the end – for himself, and for everyone who followed him to Esilio.

In the cabin, the sense of familiarity he’d gained from the rehearsals reimposed itself. Ramiro sealed the inner hatch, then clambered down a rope ladder to the nearest of the three couches behind Tarquinia’s. The couches were shaped to make more sense once the gravity was at right angles to its present direction, but for now he had to lie on his back with his legs bent and raised, his feet brushing the floor-to-be.

As he strapped himself into place, his jetpack and helmet felt like absurd encumbrances, but when he plugged his corset’s cable into the console in front of him the panel lit up in acknowledgement. When the automation could read any pattern he raised on his skin, it didn’t matter how mobile his limbs were.

‘A full crew?’ Tarquinia lamented, mock-disappointed. ‘I was hoping for an increase in my rations.’

Azelio said, ‘I’ll see what I can do once we make planetfall.’
