Yet again he congratulated himself on his foresight and his intelligence. How many other grey seers would have responded to the reports of a bunch of skavenslaves who had been driven out of the old coal mines beneath the Lonely Tower?

None of his rivals had paused to consider that there must be something important going on when the dwarfs sent an army to reclaim an old coal mine in these desolate hills. Of course, he had to admit, none of them had had the chance because Thanquol had executed most of the survivors before they had an opportunity to tell anybody else. After all, secrecy was one of the greatest weapons in the skaven arsenal and none knew this better than he. Was he not pre-eminent among grey seers, the feared and potent skaven magicians who ranked just below the Council of Thirteen themselves? And given time even that would change as well. Thanquol knew that it was his destiny to take his rightful place on one of the Council's ancient thrones some day.

As soon as he was certain the report was true he had journeyed here with his bodyguards. And as soon as he had seen the size of the dwarf encampment, he had sent a summons to the nearest skaven garrison, invoking the name of the Horned Rat and enjoining the strictest secrecy of its commander, on pain of a long, protracted and incredibly agonising death. Now the valley was all but surrounded by a mighty skaven force, and whatever it was that the dwarfs sought to protect would soon be his. This very night he would give the command that would send his invincible furry legions surging forward to inevitable victory.

A flicker of movement attracted Thanquol's attention for a moment, a flutter of red in the breeze which reminded him vaguely of something ominous he had seen in the past. He ignored it and tracked the periscope along the side of the hill, inspecting the potent dwarf-built engines. Greed and a lust to possess them filled him; ignorance of their purpose did nothing to discourage him. He knew that they simply must be worth having. Anything which could make so much noise and create so much smoke was in and of itself a thing to make any skaven's heart beat faster.

Something about that fluttering scrap of red nagged at his mind but he dismissed it. He began to draw up a plan of attack, studying all the lines of approach along the valley edges. He wished he could summon a huge cloud of poison wind and send it blowing down the valley, killing the dwarfs and leaving their machine intact. The simple beauty of the idea struck him. Perhaps he should sell it to the warp engineers of Clan Skryre the next time he was negotiating with them. Certainly a device which could pump out gas the way those chimneys pumped out smoke would…

Wait a moment! The strange familiarity of that flapping scarlet cloak sunk into his forebrain. He suddenly remembered where he'd seen its like before. He remembered a hated human who wore something very similar. But surely… it couldn't be possible that he was here.

Hastily Thanquol twisted the periscope on its collapsible frame. He heard a grunt of pain from the skavenslave to whose back it was strapped, but what did he care? The pain of a slave meant less to him than the fur he shed each morning.

With a flick of his paws he brought the lenses into focus on the source of his unease. For a shocked instant he fought down an almost overwhelming urge to squirt the musk of fear. He stopped himself only by reminding himself that there was no way that the hairless ape could see him.

Thanquol flinched and ducked his horned head down, even though his mighty intelligence told him that he was already out of sight. He looked around to see if his two lackeys, Lurk and Grotz, had noticed his unease. Their blank faces looked up at him placidly and he was reassured that he had not lost face in front of his underlings. He took a pinch of warpstone snuff to calm his shaking nerves, then offered up something which could have been a prayer, or might conceivably have been construed as a curse to the Horned Rat.

He could not believe it. He simply could not believe it! As plain as the snout on his face, he had seen the human, Felix Jaeger, when he looked through the periscope. He leaned forward and snatched another glance just to be sure. No—there was no mistake. There he stood, as plain as day. Felix Jaeger, the hated human who had done so much to thwart Thanquol's mighty plans, and who mere months before had almost succeeded, beyond all reason, in disgracing him before the Council of Thirteen!

Justifiable hatred warred with the rational instinct of self-preservation which dominated Thanquol's soul. His first thought was that somehow Jaeger had sought him out and had come all this way to thwart his schemes of glory again. The cold light of logic told him that this could not be the case. Nothing so simple could possibly be true. There was no way that Jaeger could know where to find him. Not even Thanquol's masters on the Council of Thirteen knew his current location. He had cloaked his departure from Skavenblight in the utmost secrecy.

Then the terrifying thought struck Thanquol that perhaps one of his many enemies far away, back in the City of the Horned Rat, had by some arcane means located him, and was feeding the information to the human. It would not be the first time that wicked rat-men had betrayed the righteous skaven cause for their own gain or revenge on those they envied.

The more he thought of it, the more likely this explanation seemed to Thanquol. Rage bubbled through his veins along with the powdered warpstone. He would find this traitor and crush him like the treacherous worm he was! Already he could think of half a dozen culprits who would be deserving of his inevitable vengeance.

Then another thought struck the grey seer, one which very nearly sent the musk of fear squirting despite all of his efforts at self-control. If Jaeger was present it meant that the other one was most likely there as well. Yes, it meant that most likely the only other being on the planet who Thanquol hated and feared more than Felix Jaeger was there too. He did not doubt, and nor was he mistaken, that when he next looked through the periscope, that he would see the Trollslayer, Gotrek Gurnisson.

It was all he could do to suppress the mighty squeak of rage and terror that threatened to burst from his lips. He knew he was going to have to think about this.

The bustling activity of the place became even more evident to Felix as the wagon descended into the valley. All around them groups of dwarfs moved purposefully. Leather aprons protected their burly chests. Sweat ran down their soot-smudged faces. Dozens of odd-looking implements—which reminded Felix of instruments of torture—hung from loops on their belts. Some of the dwarfs wore strange-looking armoured suits; others were mounted in small steam-wagons with forked lifting tines on the front. These machines carried heavy crates and packages along the iron rails between the workshops and the central metal structure.

All around the factory complex a shanty town had sprung up where the dwarfs apparently lived. The buildings were of wood and drystone, with sloping roofs of corrugated metal. They seemed empty, all their occupants were out at work.

Felix looked at Gotrek. "What is going on here?"

There was silence for a long moment as Gotrek appeared to consider whether he should even answer at all. Eventually he spoke in a slow, solemn voice.

"Manling, you are looking on something I had never thought to see, that perhaps only you of all your people will ever see the like of. It reminds me of the great shipyards of Barak Varr but… So many forbidden Guild secrets are being used here that I cannot begin to number them."

"All of this is forbidden, you say?"

"Dwarfs are a very conservative people. We do not care much for new ideas," Varek said suddenly. "Our engineers are more conservative than most. If you try something and it fails, like poor Makaisson did, then you are ridiculed and there is nothing worse than that to a dwarf. Few are even willing to risk it. And of course some things have been tested and because the tests failed so… spectacularly… they were forbidden to be used, by the guild. There are things here which we have known of in theory for centuries, but which only here have we dared put into practice. I know that what my uncle wants to do is considered so important that many talented young dwarfs were prepared to take the risk, to work here in secret on our great project. They think it is worth the attempt."
