Graham McNeill: Ultramarines Omnibus

Then the Raptors exploded in a series of massive detonations and Idaeus heard a thunderous boom echo back and forth from the sides of the gorge. He twisted his dying body around in time to see the beautiful form of Thunderhawk Two roaring through the gorge towards the bridge, its wing mounted guns blasting the Raptors to atoms.

He smiled through the pain, guessing the fight Uriel must have had with the pilot to get him to fly through the flak of the Hydras and down the gorge. He raised his head to the two Raptors who still stood between him and his goal. They drew their swords as Thunderhawk Two screamed below the bridge. Lascannon fire chased the gunship, but nothing could touch it.

Idaeus slumped against a black stanchion and turned his melted face back towards the two Raptors. Between them, he could see the melta charge. He smiled painfully.

He would only get one shot at this.

Idaeus raised the plasma pistol he had taken from the dead Raptor, relishing the look of terror on his enemy's faces as they realised what must happen next.

'Mission is accomplished,' snarled Idaeus and pulled the trigger.

Uriel watched the unbearably bright streak of plasma flashing towards the central span of the bridge and explode like a miniature sun directly upon the melta charge. The searing white heat ignited the bomb with a thunderclap and it detonated in a gigantic, blinding fireball, spraying molten tendrils of liquid fire.

The central support of the bridge was instantly vaporised in the nuclear heat, and Uriel had a fleeting glimpse of Idaeus before he too was engulfed in the expanding firestorm.

The echoes of the first blast still rang from the gorge sides as the remaining charges detonated in the intense heat. A heartbeat later, the bridge vanished as explosions blossomed along its length and blasted its supports to destruction. Thunderous, grinding cracks heralded its demise as giant sections of the bridge sagged, the shriek of tortured metal and cracking rockcrete filling Uriel's senses. Whole sections plummeted downwards, carrying hundreds of rebel tanks and soldiers to their deaths as the bridge tore itself apart under stresses it was never meant to endure.

Thick smoke and flames obscured the final death of Bridge Two-Four, its twisted remains crashing into the river below. Thunderhawk Two pulled out of the gorge, gaining altitude and banking round on a course for the Imperial lines. Even as the bridge shrank in the distance, Uriel could see there was almost nothing left of it.

The main supports were gone, the sections of roadway they had supported choking the river far below. There was now no way to cross the gorge for hundreds of miles in either direction.

He slid down the armoured interior of the Thunderhawk and wearily removed his helmet, cradling Idaeus's sword in his lap. He thought of Idaeus's sacrifice, wondering again how a warrior of the Ultramarines could command without immediate recourse to the Codex Astartes. It was a mystery to him, yet one he now felt able to explore.

He ran a gauntleted hand along the length of the masterfully inscribed scabbard, feeling the full weight of responsibility the weapon represented. Captain Idaeus of the Fourth Company was dead, but as long as Uriel Ventris wielded this blade, his memory would remain. He looked into the blood-stained faces of the Space Marines who had survived the mission and realised that the duty of command now fell to him.

Uriel vowed he would do it honour.

60 million years ago…

The star was being destroyed. It was a dwarf star of some one and a half million kilometres diameter and had burned for over six billion years. Had it not been for the immense, crescent-moon shaped starship orbiting the system's fourth planet and draining its massive energies, it would have probably continued to do so for perhaps another sixteen billion years.

The star generated energy at a colossal rate by burning hydrogen to helium in nuclear fusion reactions deep in its heart before radiating that energy into space. These reactions produced intense electro-magnetic fields in the star's core that rippled to the surface in seething magnetic waves.

A clutch of these surging fields erupted as a toroidal loop of magnetic flux some 200,000 kilometres in diameter, producing a dark, swelling sunspot within the star's photosphere.

This active region of magnetic flux expanded rapidly, suddenly exploding upwards from the star's surface in a gigantic flare, covering a billion square kilometres and becoming a bright curling spear of light in the star's corona. These powerful waves of electromagnetic energy and sprays of plasma formed into a rippling nimbus of coruscating light that Spiralled a snaking route towards a rune-encrusted pyramid at the centre of the vast starship. Eldritch sigils carved into the ship's side blazed with the received energies and the hull pulsed as though the ship itself was swelling with barely contained power.

Every flaring beam of light ripped from the star that washed its power over the ship shortened the star's lifespan by a hundred thousand years, but the occupants of the starship cared not that its death would cause the extinction of every living thing in that system. Galaxies had lived and died by their masters' command, whole stellar realms had been extinguished for their pleasure and entire races brought into existence as their playthings. What mattered the fate of one insignificant star system to beings of such power?

Like some obscene mechanised leech, the ship continued to suck the vital forces from the star as it orbited the planet. An array of smaller pyramids and obelisks on the ship's base rippled as though in a heat haze, flickering in and out of perception as the massive ship shuddered with the colossal energies it was stripping from the star.

Abruptly the snaking beam of liquid light from the star faded and vanished from sight, the silver ship having had its fill for the moment. Ponderously it began to rotate and dropped slowly through the planet's atmosphere. Fiery coronas flared from the leading edges of the crescent wings as it descended towards a vast, iron-oxide desert in the northern hemisphere. The surface of the planet sped by below: rugged mountains, grinding tectonic plates and ash-spewing volcanoes. The ship began slowing as it neared its destination, a sandy dust bowl with a tiny spot of absolute darkness at its centre.

The ship's speed continued to drop as the shape resolved itself into a glassy black pyramid, its peak capped in gold. Its shimmering obsidian walls, smoky and reflective, were impervious to the howling winds that scoured the planet bare. Small, scuttling creatures that glittered in the burning sun crawled across its surface with a chittering mechanical gait. Runes identical to those on the orbiting starship hummed as powerful receptors activated.

The ship manoeuvred itself gracefully into position above the pyramid as the gold cap began to open like the petals of a flower. The humming rose to an ear-splitting shriek as the smaller pyramids and obelisks on the ship's underside exploded with energy, and a rippling column of pure electromagnetic force shot straight down the black pyramid's hungry maw.

Incandescent white light blazed from the pyramid, instantly incinerating the mechanical creatures that crawled across its surface. The desert it stood upon flared gold, streaks of power radiating outwards from the pyramid's base in snaking lines and vitrifying the sand in complex geometric patterns. The enormous vessel held its position until the last of its stolen energy had been transferred. Once the gold cap of the pyramid had sealed itself shut, the ship made the long trip back into orbit to repeat the process, its intention to continue ripping energy from the star until it was nothing more than a cooling ball of inert gasses.
