Prok grunted and Ivis responded with a pointed finger, silencing him. The commander then resumed. ‘Complexity grows ever more complex, but there is a belief that civilization is a natural force, and, by extension, that justice itself is a natural force.’ He paused, and then half smiled, as if at a memory. ‘My lord Draconus was most explicit on this point. That night, he argued as if defending himself, so stern was his regard.’ Then he shook his head. ‘But at some point, civilization forgot its primary purpose: that of protection. The rules and laws twisted round to fashion constraints to dignity, to equality and liberty, and then to the primal needs of security and comfort. The task of living was hard, but civilization was intended to make the task easier, and in many ways it did – and does. But at what cost?’

‘Forgive me, commander,’ said Prok, ‘but you return us to the notion of dignity, yes?’

‘What value this “civilization”, surgeon, if it dispenses with the virtue of being civil?’

Prok grunted. ‘There is nothing more savage than a savage civilization. No single man or woman, no band or tribe, could ever aspire to what a civilization is capable of committing, not just upon its enemies, but upon its own people.’

Ivis nodded. ‘Gothos plunged to the nadir and found those very truths in that dreadful place. How was it possible, he wondered, that justice made for an unjust world? How was it possible that love could breed such hatred? The weights, he saw, were as you said, Prok. No match to the other, not by any conceivable measure. We look to humanity in the face of inhumanity, our only armour frail hope, and how often – in a civilized setting or a barbaric one – does hope fail in protecting the helpless?’

‘The pits are filled with corpses,’ Prok muttered, reaching again for the wine, though it had long since gone cold. ‘Prisoners put to the sword, a conquered city put to the torch, and those who are to die are made to dig their own graves. ’Tis an orderly thing.’

Ivis was studying the surgeon. ‘You attended the sacking of Asatyl, in the far south, didn’t you?’

Prok would meet no one’s eye. ‘I walked away from the Legion on that day, commander.’

There was a long silence that was, perhaps, not as long as it felt for Sandalath, who had seen something pass between Ivis and Prok. She did not know the name of Asatyl, nor the event of its conquest, but the surgeon’s response left her chilled.
