The fiery globe swelled, contracted, swelled again and burst open, sending an incandescent jet straight up. Burning through the top of the stone dome, it sucked back then blew an orange spurt of molten rock-glass up through the hole. It arched high across the room, solidifying into a glass lance that split down its length as it cooled, forming a pair of curving blades as sharp as a giant's scimitars.

The strange-sight that had allowed Nish to see the globe vanished so suddenly that he cried out. An attack of vertigo had him clinging desperately to the rods, his sweating hands slipping on the warm metal.

There came another molten squirt, splitting to form another pair of glass scimitars, and then another and another until the chamber was webbed with them. Nish hung suspended above a hundred razor-sharp blades. It had to be a residue of Yggur's Art – such perfect, deadly blades could not have formed by accident – but it had trapped him as effectively as any weapon of the enemy's. If he tried to get down, he'd be sliced like a slab of buffalo on a butcher's block.

Heat billowed up through the hole, streaming directly over him. His eyelids began to rasp when he blinked. After ten or fifteen minutes Nish could feel his skin drying and cracking in the heat. He was desperate for something to drink.

From his refuge he could see part of the yard. A bound and gagged prisoner was led out to its centre, surrounded by soldiers. The prisoner was an elderly woman, one of Yggur's kitchen servants. Other servants followed, each with an escort of the scrutators' finest, then several of Yggur's guard. After them came Malien, heavily bound, Gilhaelith and, to Nish's despair, a stumbling, bloody Yggur.

Each new prisoner was a further blow to his hopes. Nish counted them down, and when Flydd and Irisis were dragged into the yard, he gave a groan of despair. The scrutators had them all, from the least to the greatest. He was the only one still free. Ghorr had out-thought them. All the time that Yggur and Flydd had been planning their secret assault on Nennifer, Ghorr had been readying his own vastly superior forces. By the time Tiaan and Malien had reached Fiz Gorgo in the thapter, five days ago, Ghorr's fleet of dreadnoughts had already been on its way. The irony was bitter.
