The hallway stretched away before them, a wide colonnade lined by twin columns that were nothing less than the trunks of cedars. Each bole was at least an arm-span in diameter. The shaggy, gouged bark remained, although most of it had fallen away and now lay scattered over the floor.

Mappo laid a hand on one wooden pillar. ‘Imagine the effort of bringing these down here.’

‘Warren,’ Icarium said, sniffing. ‘The residue remains, even after all these centuries.’

‘After centuries? Can you sense which warren, Icarium?’

‘Kurald Galain. Elder, the Warren of Darkness.’

‘Tiste Andii? In all the histories of Seven Cities that I am aware of, I’ve never heard mention of Tiste Andii present on this continent. Nor in my homeland, on the other side of the Jhag Odhan. Are you certain? This does not make sense.’

‘I am not certain, Mappo. It has the feel of Kurald Galain, that is all. The feel of Dark. It is not Omtose Phellack nor Tellann. Not Starvald Demelain. I know of no other Elder Warrens.’

‘Nor I.’

Without another word the three began walking.

By Mappo’s count, the hallway ended three hundred and thirty paces later, opening out into another octagonal chamber, this one with its floor raised a hand’s width higher than that of the hallway. Each flagstone was also octagonal, and on each of them images had been intricately carved, then defaced with gouges and scoring in what seemed entirely random, frenzied destruction.

The Trell felt his hackles stiffening into a ridge on his neck as he stood at the room’s threshold. Icarium was beside him.

‘I do not,’ the Jhag said, ‘suggest we enter this chamber.’

Mappo grunted agreement. The air stank of sorcery, old, stale and clammy and dense with power. Like waves of heat, magic bled from the flagstones, from the images carved upon them and the wounds many of those images now bore.

Icarium was shaking his head. ‘If this is Kurald Galain, its flavour is unknown to me. It is ... corrupted.’

‘By the defilement?’

‘Possibly. Yet the stench from those claw marks differs from what rises from the flagstones themselves. Is it familiar to you? By Dessembrae’s mortal tears it should be, Mappo.’

The Trell squinted down at the nearest flagstone bearing scars. His nostrils flared. ‘Soletaken. D’ivers. The spice of shapeshifters. Of course.’ He barked out a savage laugh that echoed in the chamber. ‘The Path of Hands, Icarium. The gate – it’s here.’

‘More than a gate, I think,’ Icarium said. ‘Look upon the undamaged carvings – what do they remind you of?’

Mappo had an answer to that. He scanned the array with growing certainty, but the realization it offered held no answers, only more questions. ‘I see the likeness, yet there is an ... unlikeness, as well. Even more irritating, I can think of no possible linkage ...’
