'Gaius, we're going to have to do this ourselves!' he shouted. 'Make sure we've plenty of fire keeping those xenos heads down!'

Caphen nodded and began issuing curt, concise orders, with sharp chops of his hand, to the squads spread through the rabble of what could laughingly be called their landing zone.

Behind them, the wrecked Stormbird still burned from where the alien missile had blown off its wing, and Solomon knew that it was a miracle the pilot had managed to coax the stricken aircraft to stay in the air long enough to reach the floating atoll. He shuddered to imagine their fate had they plunged to the vast planetary ocean below, lost forever amid the sunken ruins of the Laer's ancient civilisation.

The Laer had been waiting for them, and now at least seven warriors were down and would never fight again. Solomon had no idea how the other assault units had fared, but couldn't imagine they had suffered any less. He risked a glance around the column, its height oddly distorted by the eye-watering curves and subtly wrong dimensions. Everything on this atoll jarred upon his sensibilities, a riotous excess of colour, form and noise that offended the senses with their sheer frenzy.

He could see a wide plaza ahead, in which a flaring plume of searing energy was enclosed by a ring of bright coral that shone with a dazzling light. Dozens of such strange plumes were spread throughout the atolls, and the Mechanicum adepts believed that it was these peculiar devices that prevented the atolls from falling from the sky.

With no major landmasses on Laeran, capturing the atolls intact was deemed integral to the success of the coming campaign. The atolls would serve as bridgeheads and staging areas for all further assaults, and Fulgrim himself had declared that the energy plumes keeping the atolls in the air were to be captured at any cost.

Solomon caught glimpses of Laer warriors slithering around the base of the energy plume, their movements sinuous and inhumanly quick. First Captain Kaesoron had personally tasked the Second with securing the plaza, and Solomon had sworn an oath in the fire that he would not fail.

'Gaius, take your men right and work your way through cover towards the plaza. Keep your head down. They're sure to have warriors positioned to stop you. Send Thelonius on the left.'

'What about you?' Caphen shouted back over the din of gunfire, 'Where are you going?'

Solomon smiled. 'Where else but the centre? I'm going to take Charosian's lot, but make sure Goldoara are in position before I move. I don't want anyone moving before we've set down a weight of fire so heavy I could walk on it.'

'Sir,' said Caphen, 'without wishing to appear impertinent, are you sure that's the right choice?'

Solomon racked the slide on his bolter and said, 'You fuss too much over making the "right" choice, Gaius. All we need do is make a good choice, see it through and accept the consequences.'

'If you say so, sir,' said Caphen.

'I do!' shouted Solomon. 'We may not be able to do it by the book this time, but by Chemos, we'll do it well! Now pass the word.'

Solomon waited as his orders were issued to the warriors under his command, and felt the familiar thrill of excitement as he prepared to take the fight to the enemy once more. He knew that Caphen disapproved of his cavalier attitude, but Solomon firmly believed that only through such testing circumstances could warriors better themselves and so more closely approach the perfection embodied by their primarch.

Sergeant Charosian edged up behind him, his veteran warriors gathered around him in the shadow of a Laer burrow complex.

'Ready, sergeant?' asked Solomon.

'Indeed, sir,' replied Charosian.

'Then let's go!' shouted Solomon as he heard Goldoara squad open up with their support weapons. The bark and thump of heavy calibre shells thundering up the road was the sound he'd been waiting for, and he slid from the cover of the pillar and charged up the centre of the street towards the crackling energy tower.

Bolts of deadly green energy flashed past him, but he could tell they were not aimed, the weight of suppressing fire keeping the aliens from showing themselves. He heard gunfire from either side of him and knew that Caphen and Thelonius were having to fight their way towards the tower. The veteran Space Marines of Charosian followed him, firing from the hip and adding to the weight of fire provided by Goldoara.

Just as he thought they might reach the spire unmolested, the Laer attacked.

Gathered together in a single system, the Laer had been one of the first species encountered by the Emperor's Children after taking their leave from the Luna Wolves and the great triumph on Ullanor. The cheers of that momentous day still rang in their ears, and the sight of so many primarchs gathered together remained a vivid, joyous memory in the minds of the Emperor's Children.

As Horus had said when he and Fulgrim had shared a heartfelt farewell, it was an end of things and a beginning of things, for Horus was now the Emperor's Regent, Warmaster of all the Imperium's armies. Now that the Emperor had returned to Terra, entire fleets, billions of warriors and the power to destroy worlds were his to command.

Warmaster…

The title was a new one, created for Horus, and its unveiling had yet to find its fit in the minds of the primarchs, who found themselves subject to the command of one who had, until then, been their equal.

The Emperor's Children had welcomed the appointment, for they counted the warriors of the Luna Wolves as their closest brothers. A terrible accident at the inception of the Emperor's Children had almost destroyed them, but Fulgrim and his Legion had risen, phoenix-like, from the disaster with greater resolve and strength. In the process Fulgrim had earned the affectionate sobriquet of ''the Phoenician''. During this time, while Fulgrim rebuilt his shattered Legion, he and his few warriors had fought alongside the Luna Wolves for almost a century.

With a stream of fresh recruits drawn from Terra and Fulgrim's home of Chemos, the Legion had grown rapidly and, under the aegis of the Warmaster, become one of the deadliest fighting forces in the galaxy.

Horus himself had praised Fulgrim's Legion as one of the best he had fought alongside.

Now, with decades of war behind them, the Emperor's Children had the numbers to embark on crusades of their own, to make their own way in the galaxy, battling alone for the first time in over a century.

The Legion was hungry to prove itself, and Fulgrim had thrown his all into making up for the time lost while he had rebuilt his Legion, seeking to push the boundaries of the Imperium yet further and prove the courage and worth of his Legion.

First contact with the Laer had come about when one of the 28th Expedition's forward scout ships had discovered evidence of civilisation in a nearby binary cluster and determined that it was a culture of some sophistication. Though initially not hostile to the Imperial forces, this alien race had reacted violently when one of the 28th Expedition's scout forces had been sent towards their home world. A small, but powerful alien war fleet had attacked the Imperial vessels as they approached the system's core world, destroying every one of them without the loss of a single vessel.

From what little information had been gathered before the scout force's destruction, the Mechanicum adepts had discovered that the aliens called themselves the Laer and that their technology was capable of matching and, in many cases, exceeding that of the Imperium.

The bulk of Laer society appeared to exist on numerous, city-sized atolls of floating coral that plied the skies of Laeran, an oceanic planet that bore all the hallmarks of a world submerged by the melting of its ice caps. Only the peaks of what had once been its tallest mountains and structures protruded from the mighty seas that covered its entire surface.
