“Yes.” I didn’t, but lying is easier than listening to explanations. I wasn’t even that interested in their boat, but it looked as though I might be trusting myself to it, and sooner than I wanted to. Twice the size of their snekkja still didn’t sound like a big ship—but the strength of the North had always been in swift boats, and many of them. I had to pray that with all that practice the damn things were at least seaworthy.

We drew up stools around a long bench, several locals wisely deciding to relocate to other tables. Snorri called for ale and sat at the head of the table, looking out across the length of it at the snekkja’s sails flapping above the harbour wall. The sky behind them held a complex mix of dark and moody clouds, some trailing rain, but all lit by the slanting rays of the afternoon sun.

“Valhalla!” Snorri swiped the first foaming tankard off the tray as the serving women brought them out.

“Valhalla!” A pounding of the table.

“A warrior fears the battle he missed. More than any fight he can make his own, he fears the fight that’s gone, that ended without him, that no feat of arms can change.” Snorri had their attention. He paused to drink deep and long. “I didn’t fight at Einhaur, but I heard the tale of it from Sven Broke-Oar, if any straight word can come from his crooked tongue.”

The crew of the Ikea exchanged glances at that, muttering amongst themselves. The tone of the snatches I caught made it clear they shared a low opinion of the Broke-Oar.

“The battle at Eight Quays I fought in. A massacre more than a battle. My survival shames me every day.” He drank again, and told the story.

The sun dropped, shadows stretched, the world went by, but unnoticed. Snorri held us under the spell of his voice and I listened, sipping my ale without tasting it, even though I had heard it all before. All of it until he reached the Black Fort.

When Snorri first saw the black spot he thought it part of dying, his vision failing as the wilderness claimed him. But the spot persisted, kept its place, grew as he staggered on. And in time it became the Black Fort.

Built of huge blocks carved from the ancient basalt fields beneath the snows, the Black Fort sat in squat defiance of the Bitter Ice, dwarfed by the vast and rising cliffs of the ice sheet just five miles to the north. In all the long years of the fort’s existence the ice had advanced, retreated, advanced again, but never quite reached those black walls, as if the fort stood as man’s final guardian against the dominion of the frost giants.

Strengthened by the sight, Snorri journeyed closer, drawing his sealskin cloak all about him, white with snow. An east wind picked up, scouring across the ice, picking up fine dry snow and driving it in eddies and streams. Snorri leaned into the teeth of the gale, the last scraps of warmth stolen away from him, each step threatening to end in a huddle from which there would be no rising.

When the fort’s bulk blocked the wind, Snorri almost toppled, as if his support had been snatched away. He hadn’t seen that he was so close, or truly believed that he would ever reach his goal. Nobody watched from the battlements. Each narrow window stood shuttered and snow-clad. No guard waited on duty at the great gates. Numb of hand and brain, Snorri stood, uncertain. He had carried no plan with him, just the desire to finish what had started in Eight Quays and what should have ended there. He had outlived two children. He had no desire to outlive Egil or Freja, only to battle to save them.

Feeble as he was, Snorri knew that he would only grow weaker waiting in the snow. He could no more scale the walls of the fort than he could climb the cliffs of the Bitter Ice. He took Hel in both hands and with his father’s axe he beat upon the doors of the Black Fort.

After an age a shutter high above broke open, scattering ice and snow upon Snorri’s head. By the time he looked up the shutters had closed once more. He pounded the door again, knowing his mind clouded with the slowness and stupidity that cold brings, but unable to think of an alternative.

“You!” A voice from on high. “Who are you?”

Snorri looked up and there in wolf furs, leaning out for a better look, Sven Broke-Oar, face unreadable in the red-gold swirl of his hair.

“Snorri . . .” For a moment Snorri couldn’t summon his full name to numb lips.

“Snorri ver Snagason?” the Broke-Oar boomed in amazement. “You vanished! Fled the battle, men said. Oh, this is most fine. I’ll be down to open the doors myself. Wait there. Don’t run away again.”

So Snorri stood, white hands tight around his axe, trying to let his anger warm him. But the cold had wrapped around his bones, sapping strength, sapping will and even memory. Cold has its own taste. It tastes of a bitten tongue. It coils around you, a living thing, a beast that means to kill you, not with wrath, not with tooth nor claw, but with the mercy of surrender, with the kindness of letting you go gentle into the long night after such a burden of pain and misery.
