Towards the end of the third day, the route sloped upward, rising in increments toward the surface. As it did so, it became more and more unclean. The roots of the petrified forest reached down through the tunnel roof. They too were stone, and they too were diseased, covered in a grey, flaking mould. And they moved. Rock twisted in pain. The roots scraped at the walls. They tortured the ceiling, dropping jagged blocks to the floor of the tunnel. The more the path went upwards, the more the roots clustered and the more they tangled the space. Stone creaked in rotten agony. Leading from the front, Dorvurn smashed at the roots with his grandaxe, while the magmadroths battered them to fragments with their claws. At one juncture where the tunnel narrowed, Karmanax reared and unleashed a torrent of flaming bile into the knot of twisting corruption ahead. The stream melted the roots to nothing, clearing the way. The magmadroth snorted in unhappy contempt at the remains as he passed through.
Ahead, the tunnel widened. The roof was higher. Twisting, grinding roots draped the walls on all sides. Thrumnor watched the shadowy movement of the roots carefully. Rhulmok’s Grognax, just as suspicious, issued a low growl with every breath.
‘The shadows are a thicket,’ Rhulmok commented.
Thrumnor grunted his agreement. Much could hide in the dense tangle.
‘There might be more than plague-ridden stone within,’ he said. The convulsion of a blighted land concealed the artistry of the Great Road of the Wyrm.
There was so much movement. All around them, the shadows bulged and turned and rustled. An attack could come from anywhere.
The attack, when it came, was from
They were nurglings, and Thrumnor had fought their kind before during some of the many failed sieges of the Krelstrag lodge. Now the daemons attacked as if the Great Road was their land, and the Fyreslayers were the invaders. They came in a tide of uncounted thousands. In moments, the floor of the tunnel was hip-deep in the mire of the beasts. With tooth and claw and crude, rusted blade, the daemons swept against the Krelstrag duardin, seeking to overwhelm them with the sheer weight of their numbers.
The Fyreslayers responded to the attack with fury. These things had made the very veins of the earth unclean, and extermination was almost too good for them. Atop Grognax, Rhulmok let loose a roar of outrage. The magmadroth echoed him. Rhulmok began to hammer a rhythm. He chanted the Krelstrag war song. The ur-gold in Thrumnor’s flesh responded, filling him with the heat of rage and strength to shatter mountains. Down the ranks of the Fyreslayers, the essence of Grimnir came to wrathful life. The sigils and runes beaten into hardy duardin flesh glowed with fury. The uncountable nurglings were the plague-tide, rising up to drown its victims. The Fyreslayers were lava, scouring all before them.
Thrumnor swept his runic iron in wide blows. He smashed swaths of nurglings with every strike. They burst apart with wet cries of distress.
The magmadroths lashed out with tails and claws, destroying scores of the abominations. They crushed the daemons beneath their paws, smearing green bodies to bubbling liquid. They spewed their bile, burning the nurglings to ash.
The warriors of the Krelstrag fyrds hurled themselves into the destruction of the unclean enemy. With axes, they cut the grey tide down. Their voices joined Rhulmok’s, and they sang their fierce joy of battle — a pure, honourable joy that drowned out the burbling, gurgling, nonsensical clamouring of the daemons.
The nurglings rushed forward again with greater force. From behind their first ranks came their leaders. Blightkings waded into the battle, each one commanding hundreds of nurglings. They were bloated, deformed. Suppurating tentacles reached out from gaping maws where stomachs should have been. Some had one eye, others three. Arms were transformed into huge pincers. As they attacked, tocsins rang. The solemn tolling reverberated against the walls of the Great Road, claiming the tunnels in the name of the Plaguefather.
‘Unholy trespassers!’ Thrumnor shouted. ‘This is Fyreslayer land. You come here only to perish!’ He ran forward at the nearest blightking. He struck with his runic iron, plunging it into a torso maw. The jaws bit down, seizing the rod, and the blightking swung a pitted axe at Thrumnor’s head. The runemaster ducked and pressed harder. The sacred metal of the iron burned through the pestilential flesh. It shattered its spine and burst through its back. Thrumnor pulled it free as the heavy corpse fell.
