speculate about a
General Theory of Power
, which would deal with nodes themselves, the several different
strong
forces they were expected to be made of, how they related to each other and, finally, how such prodigious forces might be tapped. Nunar noted, however, that nodal forces might never be tapped safely. She also mentioned the holy grail of theoretical mancers, the
Unified Power Theory
, which would reconcile all the forces mancers knew of, weak and strong, in terms of a single field. Nunar closed the section by stating that such a theory seemed as far off as ever.
Tiaan hid the book behind a loose brick in the wall, under her bed. It seemed no use at all.
She dozed briefly, her head crackling with fractured crystal dreams, to wake with the answer in her mind. She must design a device to test the faulty hedrons and read what had happened to them. Only then could she find a way to solve the problem. Sitting up in bed, Tiaan reached for slate and chalk and began sketching.
She had just completed a rough sketch, and blown out her candle, when Tiaan heard the rattle and groan of a clanker coming up the road. It had to be Ky-Ara returning. Since it was practically dawn, she dressed and went out.
A sleepy attendant with a lantern was opening the side gate as she arrived. Gi-Had was there too. He must have returned in the night. Tiaan watched the monster emerge from the dark. The clanker had covered lanterns on the front, a broad, segmented body made of overlapping plates of armour, and four pairs of mechanical legs driven by ingenious gearing. It was large enough to carry ten people and all their gear, though in bone-shaking discomfort. The shooter’s platform on top, with its mechanical catapult and javelard, was empty.
The clanker clumped into the shed and stopped. The mechanism creaked and groaned, then there was silence save for the whine of the twin iron flywheels that stored power in case the field was interrupted momentarily. The flywheels would still be going at dinnertime, slowly running down.
The back hatch opened. A slim young man climbed out, pack in one hand, a satchel in the other. He stretched, gave the machine an anxious pat on the flank and turned around.
Ky-Ara was not overly tall. His lean, handsome face was marred by a weak jaw. A shock of wiry hair stood out in all directions. His dark eyes were red-rimmed. There was a smudge of black grease across one cheek. Despite all that, Tiaan rather liked the look of him.
‘It’s good to have her whole again,’ Ky-Ara said to Gi-Had, avoiding Tiaan’s eye. ‘After the controller
died
… I thought I’d never drive her again.’
His face crumbled. The bond between clanker and operator was intense, almost like that between lovers, and a threat to it had been known to cause mental breakdown. Ky-Ara looked close to one now. Tiaan felt for him.
‘It’s been hard work getting used to the new controller,’ he continued. ‘I’ve got a shocking headache. Despatch for you, surr!’ He handed the satchel to Gi-Had.
‘Thank you.’ The overseer turned away to open it. He began to read a document, frowning as he did.
‘What happened when it failed?’ Tiaan asked Ky-Ara.
The operator’s top lip quivered but he mastered himself. ‘We were heading up the coast from Tiksi. Everything had gone perfectly. We were passing out of the aura of the Lippi node towards the Xanpt node. That’s a really strong one …’
‘So I believe,’ said Tiaan. She liked the shape of Ky-Ara’s mouth. A wonder she hadn’t noticed him before.
‘I had the controller helm on, sensing out the Xanpt field in advance. Sometimes it can be tricky shifting from one to another, and I didn’t want to get stuck between fields. The flywheels won’t drive her weight for
that
long.’
He looked sideways at Tiaan. She nodded.
‘The Lippi field began shifting wildly: sometimes strong, at other times hardly there at all. The fields grew harder and harder to visualise; I
