The wave tumbled closer, then suddenly fell away. Hulls thundered at the swift plunge, spars snapped and, on the third ship, the main mast exploded in a cloud of splintered wood. Rocking, trailing wreckage, the harvesters coasted between the piers.

Pressures drawing inward, building once more, the spirit withdrew from the bay. In its wake, devastation.

Glimmering in its obsidian world, the first ship crunched and slid against a pier, and came to a gentle rest. The white flecks of the gulls plunged down to the deck, to begin at long last their feeding. The Tarancede Tower had witnessed all, the smooth tiles near its pinnacle absorbing every flickering detail of the event, despite the failing light.

And, in a chamber beneath the old palace in the city of Letheras, far to the southeast, Ceda Kuru Qan watched. Before him lay a tile that matched those of the distant tower above Trate’s harbour, and, as he stared at the enormous black shadow that had filled the bay and most of the inlet, and was now beginning its slow withdrawal, the sorceror blinked sweat from his eyes and forced his gaze back to those three harvest ships now lolling against the piers.

The gulls and the gathering darkness made it difficult to see much, barring the twisted corpses huddled on the deck, and the last few flickering wraiths.

But Kuru Qan had seen enough.

Five wings to the Eternal Domicile, of which only three were complete. Each of the latter consisted of wide hallways with arched ceilings sheathed in gold-leaf. Between elaborate flying buttresses to either side and running the entire length were doorways leading to chambers that would serve as offices and domiciles of the Royal Household’s administrative and maintenance staff. Towards the centre the adjoining rooms would house guards, armouries and trapdoors leading to private passages – beneath ground level – that encircled the entire palace that was the heart of the Eternal Domicile.

At the moment, however, those passages were chest-deep in muddy water, through which rats moved with no particular purpose barring that of, possibly, pleasure. Brys Beddict stood on a landing three steps from the silt-laden flood and watched the up-thrust heads swimming back and forth in the gloom. Beside him stood a palace engineer covered in drying mud.

‘The pumps are next to useless,’ the man was saying. ‘We went with big hoses, we went with small ones, made no difference. Once the pull got strong enough in went a rat, or ten, plugging things up. Besides, the seep’s as steady as ever. Though the Plumbs still swear we’re above the table here.’

‘I’m sure the Ceda will consent to attaching a mage to your crew.’

‘I’d appreciate it, Finadd. All we need is to hold the flow back for a time, so’s we can bucket the water out and the catchers can go down and collect the rats. We lost Ormly last night, the palace’s best catcher. Likely drowned – the fool couldn’t swim. If the Errant’s looking away, we might be spared finding much more than bones. Rats know when it’s a catcher they’ve found, you know.’

‘These tunnels are essential to maintaining the security of the king-’

‘Well, ain’t nobody likely to try using them if they’re flooded-’

‘Not as a means of ingress for assassins,’ Brys cut in. ‘They are to permit the swift passage of guards to any area above that is breached.’

‘Yes, yes. I was only making a joke, Finadd. Of course, you could choose fast swimmers among your guards… all right, never mind. Get us a mage to sniff round and tell us what’s going on and then to stop the water coming in and we’ll take care of the rest.’

‘Presumably,’ Brys said, ‘this is not indicative of subsidence-’

‘Like the other wings? No, nothing’s slumped – we’d be able to tell. Anyway, there’s rumours that those ones are going to get a fresh look at. A new construction company has been working down there, nearby. Some fool bought up the surrounding land. There’s whispers they’ve figured out how to shore up buildings.’

‘Really? I’ve heard nothing about it.’

‘The guilds aren’t happy about it, that’s for sure, since these upstarts are hiring the Unwelcomes – those malcontents who made the List. Paying ’em less than the usual rate, though, which is the only thing going for them, I suppose. The guilds can’t close them down so long as they do that.’ The engineer shrugged, began prying pieces of hardened clay from his forearms, wincing at the pulled hairs. ‘Of course, if the royal architects decide that Bugg’s shoring works, then that company’s roll is going sky-high.’
