Barundin had no time to spare to see how his veterans fared, for something else was moving up the valley. It strode forward, a great mechanical giant, belching smoke and fire, the air around it shimmering not just with heat but also diabolical energy. Plated with riveted iron and fashioned in the shape of a great bull-headed man, the infernal machine was rocked back as a cannonball struck it in the midriff, leaving a tearing gate.
Oil spilled from the wound like blood, and smashed gears and broken chains could be seen through the rent in its armour.
‘A kollossus,’ whispered Hengrid, and for the first time ever, Barundin could detect fear in the fierce warrior’s voice. Not when they had faced the disgusting rat ogres, the whirling fanatics of the night goblins, the noisome trolls, the crackling energy of the shamans had Hengrid ever shown a moment’s hesitation; now his voice quavered, if only slightly.
From firing platforms on the behemoth’s shoulders, Chaos dwarfs spewed out gouts of fire, incinerating dwarfs by the handful as the mechanical beast stomped through their lines. Its heavy feet crushed them with every tread, while they tried in vain to pierce its armoured hide with their axes. Bullets whined from its iron plates, while shells chattered forth from a rapid-firing cannon mounted in the mouth of its bull head.
By now the cannon crews were directing all of their fire against the kollossus. One arm was ripped away, spilling burning fuel onto the ground and setting fire to its right leg. A ball trailing magical fire slammed into its knee, buckling the armour and bending the gears. Immaterial shapes began to writhe around the wounded metal beast as they escaped the enchanted machineries that held them to the Chaos dwarfs’ bidding.
A gyrocopter swept low, its cannon drilling the head with bullets, and as it lifted its way out of the creature’s outstretched hand, Barundin recognised the flying machine as the one that belonged to Rimbal Wanazaki. The king gave a cheer as the mad pilot deftly dived his gyrocopter beneath a swinging metal hand, turning in the air to fire into the exposed innards of the creature’s midriff.
Like a creature beset by ants, the immobilised machine was soon swarming with dwarfs, hacking and tearing at the metal plates of its legs, climbing up and firing with pistols into the slits and rents in its armour. Throwing axes scarred its metal skin, and soon there were dwarfs clambering victoriously into the cockpit behind the armoured face of its head. They abandoned its still, metal form, and Barundin signalled to the cannon crews behind him to deal the final blow.
One cannonball struck the metal giant square in the face, tearing the head clean away and hurling it to the ground in an explosion of flames and sparks. Its already damaged leg buckled under another impact, and with a screech of tearing metal and the tormented screams of escaping souls, the kollossus collapsed to its right, shattering upon the ground. A cheer rolled along both lines of dwarfs as the marauders began to fall back.
