Corso closed his eyes and focused on the thump of his own heartbeat, like a wet meat clock hammering out the seconds remaining before the fight. The sea hissed against the shore a few metres away. He recalled the words Breisch had repeated endlessly, until it became a kind of mantra: Death is inevitable. The key to survival lay only in giving up the fear of dying. Conversely, the key to victory lay in exploiting an opponent’s own fear of death.

Corso opened his eyes again, unable to concentrate. Instead he studied the man opposite. Breisch was hard and wiry, with gaunt features, a veteran of a hundred challenges, which made him either one of the deadliest or luckiest fighters alive on Redstone, depending on whom you asked.

It had been a considerable surprise to him when Breisch had calmly admitted, shortly after the beginning of their professional relationship, that he fully expected to die while taking part in a challenge.

‘It’s better than dying old and infirm,’ he had stated, in the same calm, clear tone he always spoke in. ‘And, frankly, I consider it vastly preferable.’

‘But you don’t have to take part in challenges any more, if you don’t want to,’ Corso had argued. Despite his long tally of violent victories, Breisch had never requested a seat in the Senate, claiming to have no interest in politics. ‘It’s hardly like anyone would blame you, after so much time. You could still honourably refuse.’

‘Because I’m old?’ Breisch smiled more easily than anyone Corso knew. ‘Even now, people still issue me challenges, because they want to be the one who finally takes me down. And one day, when I’m old enough, they’ll get their wish. I can’t imagine anything worse than retiring to some quiet life of public service. Better to go out fighting, don’t you think?’

Corso had long since got over the irony that Breisch had once trained both of the Mansell brothers, who had been part of the fateful expedition to Nova Arctis. He had since worked hard to put his resentment and anger aside, and to accept that Breisch was not responsible for the actions of either Kieran Mansell or his psychopathic brother Udo – only for the quality of their combat skills.

A little while later, they began practising some basic moves on the broken shore outside the tent, the stars clear and sharp in the evening sky.

The old man lunged at Corso with a wicked-looking blade, constantly feinting in different directions and throwing kicks and punches when they were least expected. They were both dressed lightly despite the freezing weather, so that nothing restricted their movements.
