“Shit!” That from Tuttugu as the guardsman remained standing, advanced to the wall, unsteady and clutching his arm, then turned to flee.

“Hel! Shoot him again!” Snorri shouted.

The man had descended by steps to the main wall and was running hell for leather towards the far tower where presumably his companions were housed. Why he wasn’t watching from that tower, I couldn’t tell you.

“We’re done.” I gestured at the distant wall. The man could be glimpsed every half second or so as a dark streak through the crenels notched down into the battlements.

Arne snatched his bow back, strung an arrow, and loosed it at the sky. “A pox on all the gods.” He spat and his phlegm froze before it landed.

“Why waste another arrow?” I watched the walls, wondering if they would come out to kill us or leave us to freeze.

The man fell with a thin cry, nailed as he and Arne’s arrow arrived together at the third crenel before the tower door, six yards short of his sanctuary.

“Dead-Eye!” A quad punched Arne in the shoulder.

“Dead arm if you’re not careful.” But he sounded pleased.

Snorri had already hurried away from us, towards the walls. We gave chase. It seemed to take forever to cross the hundred-yard gap. He had out a long coil of rope, knotted for climbing and stored away from the ice for this moment. At one end a grapple hook that looked suspiciously like the anchor from a small fishing boat. He threw it over the wall and it caught first time. Snorri had already reached the top as I made it to the base of the wall. A quad went up next, then Arne, then me, slipping and cursing now the knots were slippery with ice from the others’ boots. The body of the man Arne shot plummeted past me as I reached the halfway point. I bit off another complaint and kept my mouth shut after that.

With only Tuttugu yet to climb, we pulled our packs up on a rope and then hauled Tuttugu after them. That effort at last got a little warmth into my blood. I helped him to his feet after his rather undignified struggle between the battlements to reach the walkway.

“Thanks.” He grinned, a nervous thing, quick then gone, and unslung his axe from across his back. An unusual weapon, closer to the armour-piercing wedge design favoured down south.

On the gritted ice beneath my feet, spatters of the tower guard’s blood—shocking colour after what seemed an eternity of white. The droplets captured my gaze. All the talk, all the travel, had come to this moment, these crimson splashes. From abstract to real—too real.

“Are we ready?” Snorri from before the door our man had been running for. The word no fought to get past my lips. “Good.” Snorri held his axe in a double grip, Arne a broadsword, the brothers each with a double-headed broadaxe, short-handled, a knife in the off hand. I drew my longsword, last of all of them. Satisfied, Snorri nodded and set his hand to the iron door handle. The plan did not have to be reiterated. It was, as plans go, a simple one. Kill everyone.

The door opened with a squeal of hinges, shedding ice, and we were through, crowding onto the steps beyond. Snorri closed it behind us and I shut my eyes, taking a moment to enjoy the simple ecstasy of being out of that wind. No winter night of Red March had ever been as cold as it was there in that corridor within the Black Fort, but without the wind it was a paradise compared to the outside. We all took a moment, several moments, stamping a touch of life back into our feet, swinging our arms to recover a little of that lost flexibility.

Snorri led on, down the steps and into a long corridor. We expected to find most of Sven Broke-Oar’s men in one spot. It’s what men do in cold places. They huddle by the hearth, shoulder to shoulder, for as long as they can stand each other’s company. With fuel so hard to come by, they would not light many fires.

Although in many places the interior walls were ice-clad, it felt hot in the Black Fort. My skin burned with it, life creeping back into my hands and even threatening to invade my fingers.

Arne lit a small lantern, the oil carefully hoarded during our long trip for just this purpose. Perhaps with its warmth Fimm would not have died in the night. The guard had carried no source of light, knowing his path through the dark.

At each door we paused and Snorri tried the handle. None of them were locked, though some were jammed and opening them quietly tested even Snorri’s strength. The first two proved empty: long, narrow chambers with no hint of their purpose save a lack of fireplaces that told us they had never been intended for habitation. A third chamber stood stacked high with blocks of the same basalt that formed the walls themselves. Materials for repair. A fourth had been used as a latrine, though not recently; the mounds of frozen dung gave not the slightest scent.
