They resumed their journey.

The sun was bathing the slope in brilliant gold light by the time they had closed to within a hundred paces of the summit, reaching a broad ledge that seemed – through a sparse forest of straggly, wind-twisted oaks – to run the length of the valley side. Scanning the terrace’s sweep to his right, Delum voiced a grunt, then said, ‘I see a cave. There,’ he pointed, ‘behind those fallen trees, where the shelf bulges.’

Bairoth nodded and said, ‘It looks big enough to hold our horses. Karsa Orlong, if we are to begin riding at night...’

‘Agreed,’ Karsa said.

Delum led the way along the terrace. Gnaw scrambled past him, slowing upon nearing the cave mouth, then crouching down and edging forward.

The Uryd warriors paused, waiting to see if the dog’s hackles rose, thus signalling the presence of a grey bear or some other denizen. After a long moment, with Gnaw motionless and lying almost flat before the cave entrance, the beast finally rose and glanced back at the party, then trotted into the cave.

The fallen trees had provided a natural screen, hiding the cave from the valley below. There had been an overhang, but it had collapsed, perhaps beneath the weight of the trees, leaving a rough pile of rubble partially blocking the entrance.

Bairoth began clearing a path to lead the horses through. Delum and Karsa took Gnaw’s route into the cave.

Beyond the mound of tumbled stones and sand, the floor levelled out beneath a scatter of dried leaves. The setting sun’s light painted the back wall in patches of yellow, revealing an almost solid mass of carved glyphs. A small cairn of piled stones sat in the domed chamber’s centre.

Gnaw was nowhere to be seen, but the dog’s tracks crossed the floor and vanished into an area of gloom near the back.

Delum stepped forward, his eyes on a single, oversized glyph directly opposite the entrance. ‘That Bloodsign is neither Rathyd nor Sunyd,’ he said.

‘But the words beneath it are Teblor,’ Karsa asserted.

‘The style is very . . .’ Delum frowned, ‘ornate.’

Karsa began reading aloud, ‘ “I led the families that survived. Down from the high lands. Through the broken veins that bled beneath the sun ...” Broken veins?’

‘Ice,’ Delum said.

‘Bleeding beneath the sun, aye. “We were so few. Our blood was cloudy and would grow cloudier still. I saw the need to shatter what remained. For the T’lan Imass were still close and much agitated and inclined to continue their indiscriminate slaughter.”‘ Karsa scowled. ‘T’lan Imass? I do not know those two words.’

‘Nor I,’ Delum replied. ‘A rival tribe, perhaps. Read on, Karsa Orlong. Your eye is quicker than mine.’

‘“And so I sundered husband from wife. Child from parent. Brother from sister. I fashioned new families and then sent them away. Each to a different place. I proclaimed the Laws of Isolation, as given us by Icarium whom we had once sheltered and whose heart grew vast with grief upon seeing what had become of us. The Laws of Isolation would be our salvation, clearing the blood and strengthening our children. To all who follow and to all who shall read these words, this is my justification—”‘
