short, fat man hurrying behind them. A huge bunch of keys jangled at his prodigious waist, and sweat sprayed from his bald head.
âWhatâs . . . ?â he began, but his words trailed away as they reached the end of the corridor and emerged into a vast, echoing chamber. Directly ahead was the source of the light Gulph had glimpsed: a giant sphere of metal pierced through with countless circular holes from which tongues of flame licked out. This brazier hung suspended from cables and swung slowly, spitting sparks over the uneven floor.
The walls! Theyâre moving!
Blinking, Gulph slowly understood what he was seeing. They werenât walls at all, but cages crammed full of people. A spiderâs web of iron bars, intricately knotted together, behind which squirmed a tangle of arms and legs and writhing bodies. The prisoners of the Vault of Heaven.
âAny more questions?â growled the fat man, breathing rotten meat and garlic into Gulphâs face. âThe Vault looks crowded, donât it? But thereâs always room for a little one.â
He pulled Gulph away from Captain Ossilius and dragged him past the brazier toward a cell in which the shrieking prisoners were packed like fish in a barrel. As they approached, a scrawny man wearing only rags around his waist thrust a pipe-thin arm through the bars.
âGive us the freak!â he shouted. âWeâll look after him!â
âFreakâs more skinny than you, Shankers!â cackled a woman with hair like a ratâs nest.
âLooks like a frog with them bulging eyes,â called another.
âFrogâs legs for dinner,â said the man called Shankers. âFrogâs legs! Frogâs legs!â
The other prisoners took up the chant. Gulph dug in his heels and tried to free himself from the guard, but the fat manâs grip was even stronger than that of Captain Ossilius.
âBack from the bars!â he bellowed. âWretched rebels, the lot of you! Think you can fight the crown? Look at you now! You make me want to puke!â
The fat man raised his arms. The keys dangled from one hand; Gulph dangled from the other. The tremendous heat thumped inside his head. He wanted to scream. Scream and run. Then he noticed the bars werenât as closely spaced as heâd first thought. Once inside, there was a chance heâd be able to squeeze back out.
If I survive long enough.
âStop!â Suddenly Captain Ossilius was there, planting himself squarely in front of the cage. He glared down at the man, his face like stone. âYou have your orders, Blist. Now carry them out!â
Blistâs round face quivered with uncertainty. âI thought you was jesting.â
âI never jest. And you will call me âsir.ââ
âBut . . . the Black Cell? You donât mean it. Sir.â
Ossilius bent close. âThese are not my orders, Blist. These are the orders of the queen herself. Shall I explain to her that you would not carry them out?â
âNo, sir,â said Blist. His eyes, which up to now had been shining, turned cold and dead. âI would no more betray the queen than a captain of the Legion.â
âVery well. Discharge your duty, jailer, and I will discharge mine.â
Captain Ossilius swung on his heels and marched away. As he passed into the exit corridor, he paused and looked back at Gulph. He opened his mouth, about to speak, before changing his mind and stepping out of the Vault, into the dazzling day outside.
âCan you put me down, please?â said Gulph. âMy arm hurts.â
Blistâs other hand clenched around the bunch of keys, and for a moment, Gulph thought the jailer would drive them into his face. Then the fat manâs shoulders slumped, and he lowered Gulph to the floor.
âNot another sound from you, you little freak,â he growled, before dragging Gulph back past the brazier and into a narrow
