‘There shall be no trunks on this journey! I wasted half the night packing them. I was foolish listening to you, and see how I am now beset! You must make room among your own kit.’ He pointed at a heap of materials. ‘For those, do you understand?’

‘Yes, sir.’

‘Be quick about it then, before your father appears!’

Arathan went over to the objects. He studied them for a moment, considering how he might fit into his bedroll the assayer’s scales and the weights and measures. If there had been a small bag to hold the weights, it no longer accompanied them. He counted a dozen gradations of the pure metal, the heaviest feeling solid and filling the palm of his hand when he picked it up. The lightest one was barely the size of a pebble, like a thick coin. He tucked that one into his belt pouch.

At a snapping insult from Sagander, he quickly gathered up the rest of the equipment and made his way over to his horse.

The groom, a boy of about the same age as Arathan, had already strapped the kit to the gelding’s saddle, and upon seeing Arathan’s approach he made an expression of annoyance and turned to drag it free.

‘Set it down,’ said Arathan. ‘I need to fit these in.’

The groom did so, and then backed off, as if unwilling to draw too close to the strange instruments.

‘You can go,’ Arathan said to him. ‘I will do this.’

With a quick nod the boy hurried away, vanishing into the gloom of the stables.

Arathan loosened the careful knots he had tied to secure the bedroll. He’d already packed his change of clothes inside, including a new pair of henen hide boots. As the boots were heavy he had been careful with the balance, since Raskan had told him that horses were easily irritated by such things, especially over a long trek. Pulling the tie-strings clear, he unfurled the bedroll. He laid out the measures and the weights, but the scales were too large to fit. As he knelt, contemplating what to do with the awkward instrument, he became aware of a general silence in the courtyard, apart from the heavy approach of boots. A shadow fell over him and Arathan looked up.

‘Why are you not ready?’ Lord Draconus demanded.

At the question, Arathan felt his throat tightening, choking the words from him. He continued peering upward, silent.

He saw his father’s eyes shift to the scales on the ground beside Arathan, and then he reached down and picked them up. He held them out to one side. A servant appeared to take the instrument from him and hurry off, back towards the house. ‘There is no time for this,’ Draconus said, turning away.

Arathan watched his father walk back to Calaras. The servants in the courtyard all stood with bowed heads. Tutor Sagander was already beside his own mount, glaring across the distance at Arathan.

He quickly rolled up the bedding, leaving the weights and measures in place. He tied rough knots to bind the kit and lifted it to the back of the saddle. He struggled for a time with the straps; his hands felt clumsy, almost useless, the tips of his fingers too soft and yielding since they lacked most of their nails. Finally, he fumbled his way through and stepped back. Facing round he saw that his father was now astride Calaras, reins in gloved hands. Raskan was pulling himself on to his own mount, while two servants helped Sagander do the same. By the gate, the Borderswords had vanished and no doubt now waited outside.

Arathan took up Besra’s reins, which had been left to dangle. He had to grope to slide his boot into the stirrup, almost losing his balance, and then he pulled himself up and on to the saddle.

Draconus led them out through the gate, followed by Raskan and then Sagander, who curtly waved Arathan into his wake.

Glancing back, a moment before the gate’s shadow fell over him, Arathan saw his half-sisters, atop the steps before the door of the house. They were in their nightclothes: loose and flowing and black as ink. Above this filmy darkness their faces seemed deathly pale. A faint shiver ran through him at the sight, and then he faced forward once more and, trailed by his charger on a long lead, rode out from the courtyard.

The Borderswords were mounted on dun-coloured horses, the beasts lighter-boned yet longer-legged than the stable horses being ridden by those of the Lord’s household. In addition to their riders, the animals carried bundled tents and cookware, as well as packs bulging with dry foods and casks of water.

Feeling uncomfortable, burdened by the armour and the heavy helm on his head, Arathan guided his horse after Sagander — until without warning the tutor reined in. Besra edged deftly around the sudden obstacle, only to draw up when Sagander reached out and took hold of the bridle. ‘Look back, student. Go on, do as I say.’
