The apprentice grinned. 'Strange and sinister was the host that Glustrod gathered. He waited for Juvens to leave the Empire, then he crept into the capital at Aulcus and set his well-laid schemes in motion. It seemed as if a madness swept the city. Son fought with father, wife with husband, neighbour with neighbour. The Emperor was cut down on the steps of his palace by his own sons and then, maddened with greed and envy, they turned upon each other. Glustrod's twisted army had slithered into the sewers beneath the city and rose up, turning the streets into charnel pits, the squares into slaughter yards. Some among them could take forms, stealing the faces of others.'

Bayaz shook his head. 'Taking forms. A dread and insidious trick.' Logen remembered a woman, in the cold darkness, who had spoken with the voice of his dead wife, and he frowned and hunched his shoulders.

'A dread trick indeed,' said Quai, his sickly grin growing even wider. 'For who can be trusted if one cannot trust one's own eyes, one's own ears, to tell friend from foe? But worse was to come. Glustrod summoned demons from the Other Side, bound them to his will and sent them to destroy those who might resist him.'

'Summoning and sending,' hissed Bayaz. 'Cursed disciplines. Dire risks. Terrible breaches of the First Law.'

'But Glustrod recognised no law beyond his own strength. Soon he sat in the Emperor's throne room upon a pile of skulls, sucking the flesh of men as a baby sucks milk, basking in his awful victory. The Empire descended into chaos, the very slightest taste of the chaos of ancient days, before the coming of Euz, when our world and the world below were one.'

A gust of wind sighed through the chinks in the ancient stonework around them, and Logen shivered and pulled his blanket tight around him. Damn story was making him nervous. Stealing faces, and sending devils, and eating men. But Quai did not stop. 'When he found out what Glustrod had done, Juvens' fury was terrible, and he sought the aid of his brothers. Kanedias would not come. He stayed sealed in his house, tinkering with his machines, caring nothing for the world outside. Juvens and Bedesh raised an army without him, and they fought a war against their brother.'

'A terrible war,' muttered Bayaz, 'with terrible weapons, and terrible casualties.'
