At Berliaas, desperate crowds demonstrated outside the governor's palace, demanding action be taken to evacuate the populace. Tempers flared and thousands of angry citizens stormed the palace only to find the planetary governor had already fled Chordelis and that his missives for calm had been broadcast from off-world.

In Dremander, the crew of a rogue trader's vessel opened fire on people trying to commandeer their vessel, killing more than seventy before being overrun and torn to pieces by the angry mob.

Two days after this incident, more than eleven thousand people died at Jaretaq, the planet's largest port, as terrified crowds broke through the lines of Arbites guarding the entrance and demanded passage on the fleet of departing vessels thronging her landing platforms. As the luxury vessel Cherrona lifted from the planet's surface, angry crowds prevented the ground crews from releasing her mooring cables. Her starboard engine was torn free of its mountings as her captain brought her about for departure. The engine dropped and blew apart like a bomb among the milling crowds and the ponderous vessel began sliding back towards the ground, the attraction of gravity too much for its remaining engine to fight. Fully laden with refugees and thousands of tonnes of fuel, the Cherrona swayed drunkenly in the air, striking the nearby control tower before slamming into the landing platforms of the spaceport.

The Cherrona exploded with the power of an orbital bombardment, hurling blazing sheets of fire and lethal fragments in all directions, scything through thousands of people and touching off scores of secondary explosions. The devastation ripped through the spaceport until almost nothing was left standing. The blazing pyres of this terrible disaster could be seen as far away as the planetary capital of Kaimes.

All across Chordelis, the same scenes played out as its terrified population fought to escape their doomed world.

The command bridge of the Vae Victus was tense and subdued as Admiral Tiberius kept his ship a respectable distance from the mighty structure that slid through space before them and filled the viewing bay. They had all heard of the disaster at Yulan and the loss of the third refinery, and Tiberius was determined that nothing similar would happen to this one.

'How close are we, Philotas?' whispered Tiberius, as though the volume of his voice would alert the tyranids to their presence, though the aliens must surely be aware of them by now. Garbled reports from Arx Praetora squadron and the Dauntless cruisers, some thirty thousand kilometres ahead of them, had spoken of the alien fleet moving in a solid mass of creatures, several hive ships scattered throughout the swarm. They were probably too far apart to catch more than one or two, but even one was a victory.

'Hard to say, admiral,' replied Philotas. 'Surveyor returns are being scattered by the refinery vessel, but I'd say no more than fifty thousand kilometres.'

'We're cutting this very close,' observed Uriel, staring at the plotting table. 'The first engagements at Barbarus were not much closer than this.'

'I know, Uriel, I know. But we only have one chance at this. Chordelis is depending on us. We cannot fail.'

Uriel nodded, determined that Chordelis would not suffer the horrible fate of Barbarus Prime. By now there was nothing left of that world but a dead hunk of rock, its people, wildlife and very ecosystem devoured by these monstrous aliens. Chordelis also faced obliteration, but in this case the threat did not come from the aliens, but from the very people supposed to be defending it.

The thought of Kryptman's cold, steel logic sent a shiver down Uriel's spine and he was reminded of the last time he had defied the will of an inquisitor. On this very ship, Inquisitor Ario Barzano had proposed the destruction of Pavonis to prevent a madman from obtaining a weapon capable of unmaking the stars themselves. Uriel had managed to persuade Barzano to give them one last chance to act and, by the grace of the Emperor, they had been successful, and Pavonis had been spared the horror of the ultimate sanction of viral bombing.

Once again he had been forced to stand against those he would have counted as his allies in defence of the ordinary men and women of the Imperium. It astounded him that Kryptman could be so unfeeling with the lives of millions of people, consigning an entire planet to death simply to prevent the enemy from taking it.

Only two days ago in the captain's chambers on the command deck of the Argus, Kryptman had told them of his decision to let Chordelis die.

'We have no choice,' the inquisitor had said. 'Fighters from the Kharloss Vincennes have harried the vanguard of the alien fleet from Barbarus, past Parosa and Yulan. 'The tyranids will be here within three or four days at the latest. There is simply no more time to get anyone else off Chordelis. If we stay any longer we will doom what little assets we have, and for what? We could fight, and we would gain perhaps a day's respite for the defenders on Tarsis Ultra. And once we are defeated, the tyranids will devour Chordelis as they did Barbarus Prime, swelling their numbers with an entire planet's biosphere.'

Kryptman shook his head. 'No, far better Chordelis dies by our own hand than that of the Great Devourer. Believe me, Exterminatus is a better, quicker death than the tyranids will offer.'

A stunned silence had greeted Kryptman's pronouncement. Admiral Bregant de Corte blanched and took a sip of amasec before taking a deep breath and casting his flinty gaze around the table. His assembled captains looked shocked, but took their lead from the admiral and said nothing. Captain Gaiseric and Astador nodded slowly.

Admiral Tiberius cleared his throat and leaned forwards, resting his elbows on the smooth table and steepling his fingers before him.

'There must be another way,' he said slowly, and Uriel was struck by yet another sense of deja vu, remembering when Inquisitor Barzano had come to a similar decision.

'Admiral Tiberius is correct,' he said. 'What is the point of us being summoned to this system to defend it when our first reaction to these aliens' advance is to destroy everything in their path? You would have us stand victorious over a dead system.'

'You do not see the larger picture, Captain Ventris,' said Kryptman, emphasising the insignificance of his rank next to his own. 'We are at war with forces too terrible to comprehend, and one must sometimes sacrifice the smaller battles to be victorious in the larger war.'

'Listen to yourself,' snapped Uriel. 'You talk of sacrificing smaller battles. Do you not realise that you are talking about one of the Emperor's worlds, still populated by millions of His subjects, His soldiers? I think that it is you who forgets the "larger war".'

'No, Captain Ventris,' said Kryptman with finality. 'I do not.'

Uriel stood and slammed his fist on the table, splintering the wood. 'Every time these aliens invade the Emperor's realm we fall back. People like you claim we cannot fight them and we hear this so often we start to believe it. Well that stops now. I say we draw a line here and talk no more. This time, I say we stand and fight.'

'Captain Ventris, you forget your place,' said Chaplain Astador. 'We are here to fight the tyranids and if the learned inquisitor believes that this is the best course, who are you to question him?'

'I am a loyal servant of the Emperor and proud son of Roboute Guilliman. As I once thought you to be, and the fact that you even ask me that question shows me how wrong I was.'

Astador's face filled with thunder and the muscles along his jaw bunched in rage at Uriel's insult.

'While we are united in a common cause, I shall call you brother, but when this foe is defeated, there will be a reckoning between us,' promised Astador.
