In desperation the Shadow clambers after me, but a funnel has formed in the water beneath the broken lodestone. It stretches far down and whirls violently, creating a magical vacuum which drags at the mass of shadows. The beast's rear tentacles are stiff behind it, drawn towards the vortex, and its body begins to lengthen and narrow. The creature strains against it, but the vacuum is too strong. There are laws which even the Shadow has to obey, at least for the time being.
In a rush, and with a hateful shriek, the Shadow's ripped away. It smashes through the lodestone, shattering the remains of the rock, and disappears down the funnel, howling all the way. Moments later the funnel collapses in on itself as swiftly as it formed.
I want to rush to Beranabus's corpse and bid him farewell. I'm weeping and all I want is to be by my dead friend's side. But that's not possible. Because now that the lodestone's magic has evaporated, the shield keeping the sea at bay has started to give way.
The fragments of the lodestone fall first, trickling through cracks in the invisible barrier. Water seeps up through the cracks, spreading neatly across the surface of the shield. Then one of the living dead stumbles and drops out of sight as if crashing through a thin layer of ice.
"Let's get the hell out of here!" Dervish shouts, hauling me through the door.
"Beranabus!" I cry.
"We can't help him now," Dervish pants. As he says it, the shield flickers out of existence and water floods the hold.
The ship lurches. A wave of foaming water surges towards us, washing away the helpless bodies of the zombies. We should be washed away too, but Sharmila acts swiftly to avert catastrophe, establishing a barrier around us and the doorway. The wave breaks and seethes away, the sea temporarily cheated of its victims.
"Quick," Sharmila gasps, hopping up the stairs. "The magic is fading. The barrier will not hold."
She's right. I can feel the energy ebbing away at a frightening rate. I look one last time for the body of Beranabus, but the ocean has already claimed it. Wiping tears from my cheeks, I hurry after Dervish and Sharmila, knowing that if we don't climb sharply, we'll soon be joining Beranabus in his watery grave.
We move a lot slower going up than we did coming down. It's not just the fact that we're climbing. We're tired and drained. We were fine when the air was thick with magic, but the unnatural energy is fading fast.
We're halfway up the second flight of stairs when I hear the sea gush up the corridors behind us. I've no idea how long we have. I imagine it would usually take a ship this size at least a couple of hours sink, but the hole in the hull was extremely large.
The zombies are still going strong. The strange magic of the Shadow which reanimated them is fading slower than the energy we were tapping into. While we're rapidly weakening, the zombies haven't been significantly affected.
We don't use bolts of magic anymore, or arrogantly dismiss them with a wave of a hand. We're reduced to close-quarters fighting. We can still repel them with our charged fists and feet-the magic hasn't disappeared entirely-but there are thousands of zombies. If we're still here when the last of the energy fades, they'll swamp us. Unless the sea claims us first.
Sharmila's second leg fragments. She pumps magic into it to hold the bones and scraps of flesh together.
"Don't bother," Dervish grunts, lifting her. "Save your strength. Get on my back. I'll be your legs. You keep the zombies off."
"What about your heart?" Sharmila shouts.
"It'll hold for a while."
I can move much quicker than Dervish now that he's burdened with Sharmila. I'm tempted to race ahead of them, up through the ship, away from the encroaching water. But they're my friends and they wouldn't desert me if I was in their position. If it becomes necessary to flee, I will. But as long as there's a chance we might all make it out alive, I'll stick with them.
I take the lead, knocking flailing, snarling zombies out of our way, pushing ahead, the undead humans crowding the staircase behind and in front. I should feel fear in the face of such warped, nightmarish foes, but my emotions are focused on Beranabus-there's only room within me for mourning.
I can't believe he's dead. It's hard to imagine a world without the ancient magician. He's been mankind's saviour for longer than anyone should have to serve. What will we do without him? I doubt the Disciples can repel the waves of Demonata attacks by themselves. Beranabus believed our universe created heroes in times of need. If that's true, perhaps someone will replace him. But it's hard to picture anybody taking the magician's place. He was one of a kind.
We hit another level. I'm about to lurch up the next set of stairs when I spot Kirilli Kovacs tussling with a gaggle of zombies. He's in bad shape, bitten and scratched all over. A dozen of the living dead surround him.
I should leave him. He doesn't really deserve to be rescued and I can't afford to waste any of my dwindling power. But I can't turn my back on a man just because he's a coward. Kirilli didn't betray or undermine us-he simply gave in to fear, as many people would have.
Drawing on my reserves, I mutter a spell and gesture at the zombies packed around Kirilli. They fly apart and a path opens. "Run!" I yell. Kirilli doesn't need to be told twice. He stumbles clear of the zombies and is by my side moments later. Blood cakes his face, but his eyes are alert behind the red veil. He starts to say something.
"No time for talking," I snap. "Get up those stairs quick, and if you fall, I'll leave you."
Kirilli flinches, draws a breath, then darts ahead of me, taking pole position, staggering up the seemingly endless flights of steps towards the upper deck and its promise of escape.
As we're forcing our way up another staircase clogged with zombies, Dervish gasps and collapses to his knees. One hand darts to his chest. I think it's the end of him, but Sharmila presses her hands over his and channels magic into his heart. She pulls a stricken face as she helps-the magic she's directing into his flesh means she has less to ward off the pain in her legs. But she has no real choice. Without Dervish to carry her, she's doomed.
