The Aral Pass carries me a third of the way across the Slidr. I find my focus and realize the river’s sharp load has not yet cut me open but there’s still too far to go and the opposite shore is slipping by too fast. In the distance I hear a roar, a low, steady, wet-mouthed roar. A long silver spear passes beneath me, too close. I start to swim again, pounding artlessly at the water, and this time it is the bloodshed at the Black Fort that drives me on. I remember the sick sound as my sword point pierces an eye, crunching through the bony orbit and into the Viking’s brain. In an instant the fire is gone from him, a meat puppet with his strings all snipped. An axe cleaves the air in front of my face as I sway back. A high table catches me in the back and I topple onto it, twisting, throwing my legs into the spin. A broadsword hammers into the planks where my head was and I’m over the table, on both feet, swinging, shearing through the arm that held that sword.

The battle madness of the Black Fort releases me at last, panting amid tumbled corpses. I’m two-thirds of the way across the Slidr, still in the choppy, swift-moving clarity of the river. Downstream, in the distance, the valley is choked with mist. That roar has grown louder, filling the world, trembling in the depth of my bones.

I strike out for shore, desperate now. Something bad waits for me in that mist but I’m running out of fight and time. The coldness takes me and all I have to burn is my duel with Count Isen, the high, sharp crash of blade on blade as he tries to kill me and I weave my defence from desperation. It’s not enough. I’m still ten yards from shore and going under. There’s a sharp agony in my leg that reaches me even though the limb is frozen and numb. I’ve been hit. The waters close over me. I surface once more and see that before reaching the rising mist the whole Slidr vanishes as if itself cut by a massive sword. The thunder is louder than thought. I’m being dragged to the falls. I go under again and none of that matters: a shoal of knives is bearing down on me and I’ve no air to scream with.

Somehow, against all sense, my sword is in my hand. A fine way to drown. But then I remember it’s not my sword and the heat that was in my blood in the moment I took it fills me once more. Edris Dean wielded this sword against me, seeking my life as he had sought that of my mother, and of my sister, warm in the womb. I battled him before Tuttugu’s corpse. The corpse of my friend, a coward who died a hero’s death. I remember how it felt to drive my sword between Edris Dean’s ribs, to sink it into the meat of him, to feel it bedded in his flesh and to rip it out again, grating across bone. I open my mouth and roar, careless of the river, and there I stand, dripping in the shallows, sword in hand, and above me the mist from an endless waterfall rises in clouds that dare the sky. The Slidr plunges over a rocky lip just ten yards on. Swords leap from its clear waters as gravity takes the river and hauls it swiftly away.

I step forward on trembling legs, weak in every limb, three more steps, two more, and I’m on the wet sand. I’ve no injuries that I can see.

A figure is running toward me, Snorri, slowing as he draws near, panting. “I—” He raises a hand, draws in a huge breath, “thought I’d lost you there.”

I look at the sword in my hand, the script etched into its blade, the water still dripping from it, diamonds turned rust red in the deadlight. “No. Not yet. Not today.”

We climb up the riverbank in silence, both of us wrapped in memories. As the Slidr dries from me I feel that somehow its waters have left me more . . . connected. I remember my battle at the Aral Pass. I remember the fight within the Black Fort. For the first time Jalan the berserker has met everyday Jalan and we’ve come to some sort of agreement. I’m not sure exactly what it is yet . . . but something has changed.

Hell on the far side of the Slidr proves steeper than before. Hills of black rock replace the dust, hills in which everything is sharp and that offer a traveller no chance for rest. Everywhere the stone looks as if it were soup on the boil, frozen in the instant, bubbles bursting from it, leaving a myriad edges, all razored. Just touching the ground leaves my fingers bloody. How long the leather soles of my boots will last, and what will become of my feet after that, I can’t say.

We see more souls here, grey clusters of them, flowing like dirty water along the dry valleys, men and women and children, heads down, unspeaking, drawn onward by some call I can’t hear.

We follow, twisting and turning through the black hills, the valleys becoming deeper, broader, more thick with souls. The Slidr is less than a memory now, Hell has parched me again. I feel my skin dying, desiccating, flaking away.
