Perhaps Muller had even been sane when he came here, but had been driven mad by a diet that must have consisted of tainted flesh and warpstone-corrupted water. Felix did not want to consider that this might be the only option open to him and his companions too, if they did not find a way out of here soon. At the moment, death seemed preferable to such an existence but who could tell? Perhaps it would become easier as your brain degenerated and warpstone-inspired madness consumed the mind. Perhaps you might even come to enjoy it. Once more he forced the thought from his head—and as he did so he realised that the staircase had finally come to an end.

Up ahead Gotrek stood in front of a massive archway. The lintel was covered in a mass of carved daemon heads. They smiled mockingly, bared monstrous fangs, stuck out their tongues. Their expressions were crazed and debauched and full of madness and Felix wondered at the minds which could have carved such things. The archway itself was sealed by an enormous slab of stone inscribed with the twisted characters that Felix had come to associate with the followers of the Dark Powers of Chaos. It was becoming increasingly obvious that this part of the ruined city, at least, had long been home to the slaves of Darkness.

Gotrek reached out and pushed the stone but nothing happened. The slab did not budge. Slowly the Slayer applied more and more pressure until the huge muscles swelled and rippled all along his back and arms. Sweat beaded his forehead and his breathing came in ragged gasps. Snorri joined him but even their combined strengths had no effect on the archway. Felix did not even bother to try and help them. There was not enough room for him to squeeze in between them, and anyway, he doubted that his efforts would count for much compared to the amount of force the two dwarfs were bringing to bear.

Eventually Gotrek gave up. He stood back and scratched his head with one massive hand. He picked up his axe and looked as if he was considering swinging it at the door but then he simply grinned and reached out to touch one of the leering daemon heads carved on the lintel. He pushed down on the tongue. It moved and as it did so the archway swung open, sending the still-straining Snorri sprawling through it to land flat on his face on the dusty flagstones beyond.

"No damage done. He landed on his head," Gotrek muttered and strode through. With a last glance at the galleries behind them, Felix hastily followed.

They emerged onto a wide flat space open to the sky. Ahead of them was a walled barrier like a battlement. Behind them was a massive wall. Felix strode forward to the barrier and looked down. At once he realised that they were on the penultimate level almost at the very top of a massive ziggurat, for below them were all the lower steps. Close by was a flight of monstrous stairs leading all the way back down to the ground. The stairs also led up to a peak of the pyramid, and Felix hastily climbed them. At the top was a great open ledge. It was old and crumbling and it extended out over a wide expanse of empty air. Felix gingerly walked to the edge and looked down.

A long way below him was the pool in which the monstrous thing had dwelled and all the galleries in which the Chaos harpies had nested. There were chains and manacles along the walled edges of the ledge, and a slow realisation of the platform's function came to him. This was a place of sacrifice. Living victims had once been brought here and then thrown screaming from the ledge to tumble into the pool below, where the dweller in the murky water devoured them. It must have been an unpleasant fate, and Felix wondered about the sanity of those who had devised it.

Had this whole vast ziggurat been built purely with this function in mind? Or it had it once served a different purpose and become corrupted as the foul power of Chaos spread across this ancient land? Was it even possible, as Gotrek had suggested earlier, that this whole structure had been created by whim of one of the Dark Gods or their daemonic servitors?

None of his thinking was going any way towards finding salvation, Felix decided. They had found the open air but they had no idea where the airship was or how they could locate it. And if they failed to do that they were doomed.

He turned back from the vertiginous drop and scanned the horizon. Surely, he thought, if the airship was still over the city, it would be visible. He squinted in the strange light filtering through the clouds and tried to concentrate, wishing all the while that he still had the telescope that he had left on the ship. All he could see was the cloud of harpies circling high above them.

Then, to his amazement, far off in the distance, he saw a small dark speck that seemed to be moving in their direction. He prayed fervently to Sigmar that it was the Spirit of Grungni. Then he raced over to the outside edge of the ziggurat's uppermost level and shouted for the dwarfs to come and join him. But even as he did so, he noticed that an enormous horde of beastmen had emerged from the nearby buildings far below and were racing along the streets towards the ziggurat. Over their heads fluttered two harpies, screaming in their foul tongue.

Doubtless they were the things which had attracted the beast-men's attention. Before he could throw himself flat, one of the bestial Chaos worshippers noticed him, for it brandished its spear in the air and pointed with one outstretched arm towards Felix. The whole disgusting horde let out a howl of triumph and began to hurry up the long stairway towards them. Felix cursed his luck and went to join Snorri and Gotrek.

The two Slayers seemed profoundly indifferent to the fact that several thousand beastmen were racing towards them, too many for even such formidable warriors as themselves to slay.

"The stairway is a good point to make our stand," observed Gotrek. "Narrow. Not too many of them can get to us at once. Good killing."

"Hardly seems fair," Snorri said. They'll be tired by the time they get to us. All that running and then all those stairs. Maybe we should go down and meet them halfway."

"They're spawn of Chaos. I will do nothing to oblige them."

"Fair enough. Snorri sees your point."

Felix shook his head in despair. He was going to die, and he was going to die in the company of two maniacs. It was too much. He had survived evil magic, the attacks of a tentacled monster and a flock of mutant harpies only to be brought down at the last by a horde of shambling, misshapen monsters, beasts that wore the shape of men.

He turned his head to the heavens to ask blessed Sigmar to simply smite him down and get it over with when he noticed that the dot in the distance had swollen into the definite outline of the airship. It was heading directly in their direction. Felix looked down the ziggurat again. The beastmen were almost halfway up it. He glanced back at the airship. It was much further away than the beastmen, but it was moving much faster. He hardly dared hope that it would reach them in time.

The beastmen were well up the steps now, an onrushing tide of twisted flesh, brandishing spears and howling war cries. Felix could distinctly hear the clatter of hooves on the stone stairs. His heart raced. His mouth felt dry. This was almost worse than certain death. Now there was a faint hope that they might get away.

The airship swept low over the beastmen. Felix could see that the outside had been cleaned and all the engines were working. The rips in the gasbag had been repaired. He would not have believed that it was possible for so much work to be done in so short a time. The dwarfs had certainly been busy. He could see now that the doorways in the side of the ship were open as was the hatch in the bottom. Someone had thrown open the portholes as well, and a rain of black spheres was descending on the onrushing horde. One of them burst in the air sending shrapnel everywhere. Beastmen howled in agony. Felix realised that the dwarfs on the ship were dropping bombs!
