Duiker scowled. He hated tunnels. No, they terrified him. There was nothing rational in it – wrong again. Tunnels collapse. People get buried alive. All perfectly reasonable, possible, probable, inevitable.

Nil led the way, slithering down and out of sight. The other warlock quickly followed. Lull turned to the historian and gestured him forward.

Duiker shook his head.

The captain pointed at him, then pointed to the hole and mouthed Now.

Hissing a curse, the historian edged forward. As soon as he was within reach Lull’s hand snapped out, gathering a handful of dusty telaba, and dragged Duiker to the tunnel mouth.

It took all his will not to shriek as the captain unceremoniously stuffed him down into the tunnel. He scrambled, clawed wildly. He felt his kicking heel connect with something in the air behind him. Lull’s jaw, I bet. Serves you right, bastard! The rush of satisfaction helped. He scrabbled past the old flood silts and found himself cocooned in warm bedrock. Collapse was unlikely, he told himself, the thought almost a gibber. The tunnel continued to angle downward, the warm rock turning slippery, then wet. Nightmare visions of drowning replaced collapsing.

He hesitated until a sword point was pressed against the worn sole of his moccasin, then punched through to jab his flesh. Whimpering, Duiker pulled himself foward.

The tunnel levelled out. It was filling with water, the rock bleeding from fissures on all sides. The historian sloshed through a cool stream as he slithered along. He paused, took a tentative sip, tasted iron and grit. But drinkable.

The level stretch went on and on. The stream deepened with alarming swiftness. Soaked and increasingly weighed down by his clothing, Duiker struggled on, exhausted, his muscles failing him. The sound of coughing and spitting behind him was all that kept him moving. They’re drowning back there, and I’m next!

He reached the upward slope, clawed his way along through mud and sifting earth. A rough sphere of grey fog appeared ahead – he’d reached the mouth.

Hands gripped him and pulled him clear, rolling him to one side until he came to rest in a bed of sharp-bladed grasses. He lay quietly gasping, staring up at the mist’s low ceiling above him. He was vaguely aware of the marines clambering out of the tunnel and forming a defensive cordon, breaths hissing, their weapons dripping muddy water. Those crossbow cords will stretch, unless they’ve been soaked in oil and waxed. Of course they have – those soldiers aren’t idiots. Plan for any eventuality, even swimming beneath a dusty plain. I once saw a fellow soldier find use for a fishing kit in a desert. What makes a Malazan soldier so dangerous? They’re allowed to think.

Duiker sat up.
