The First Heretic

False angels walk in our midst, cast in your image but bringing none of your mercy. They call themselves the XIII Legion, the Warrior-Kings of Ultramar, and have spoken only threats of bloodshed and sorrow since they darkened the skies a week before. Their warriors have walked the streets of Monarchia, forcing the people to abandon the city. Those who resisted were butchered. Fate willing, they will be remembered as martyrs.

Monarchia is not alone. Sixteen cities across the planet stand empty, likewise swept clean of life.

For many days, we were silenced, unable to call out to you. The XIII Legion has allowed us this moment, in the hours before the last dawn. They have vowed to end the perfect city in a storm of fire as the sun rises this very day. Return to us, we beg you. Return to us and make them answer for this injustice. Avenge the fallen, and restore what will be lost when the horizon lightens.

Bearers of the Word, hear our prayer.

Return to us, sons of the God-Emperor, blessings upon His Name. Retur–’

– First and only distress call sent from

Monarchia, capital of Khur.

Cyrene’s reckoning took two months to arrive. Almost nine weeks of lancing headlong through the tides of unspace, breaking through the immaterium with little thought of safety or control. They lost vessels. They lost lives. But they lost no time. Reality trembled in their wake.

The first ship to burst from the immaterium ripped back into reality on tormented engines. As it accelerated from the wound of re-entry, it seemed cast from the warp like a grey spear, trailing plasma mist the colour of madness. Its engines roared heavy and hot into the silence of space.

Along its ridged spine, statues of marble and gold stared out into the starry void. Armoured buildings of worship rose like overlaid carbuncles from the vessel’s skin. Battlements lined the walls of those cathedrals, and dozens of lesser temples were decorated with banks of weapon turrets in their tallest towers. The vessel, terrible in size and grim in aspect, was more a bastion city of prayer and warfare than a spaceborne vessel.

Its dangerous momentum sent shudders through its metal bones, and still it didn’t slow down. Blue-white engine wash streamed in disintegrating smoke trails from immense boosters that had taken decades to construct, by thousands of labourers working millions of hours. The ship’s prow was fashioned into a colossal ram – an eagle figurehead, wrought in dense metals polished to a silver sheen. In its talons, the eagle held the steel-forged icon of an open book. The beast’s head was frozen open in a silent shriek. Its cold eyes reflected the stars.

Other ships arrived, rending reality, breaking from the warp as lesser blurs of grey – a volley of arrows that eclipsed the stars around them. A few at first, then a dozen, soon a fleet, at last an armada... A hundred and sixteen ships, one of the greatest coalitions of force the human race had ever assembled. And still more arrived, savaging the layer between realms, dropping from the immaterium, attempting to race alongside their glorious flagship.

The grey armada moved in loose formation, the slower vessels falling behind as over a hundred ships closed in on a single blue-green world.

A world already surrounded by another battlefleet.

One of the armada’s vessels – a ship mighty enough in its own right, but utterly dwarfed by the flagship at the fleet’s vanguard – was the battle-barge De Profundis. In Low Gothic, its name translated with ragged eloquence into ‘Out of the Depths’. In the Colchisian dialect of the warship’s home world, it translated from those proto-Gothic roots as ‘From Despair’.
