The sense of violation was horrific.

She screwed her eyes shut and wept as the sensation crawled around her mind, teasing open every dark and secret place of her soul.

Then, as suddenly as it had begun, the loathsome exploration was done.

Oh yes, you are ripe, little Larana. You have a fecund and inventive hate. You shall be my greatest work…

'Stop speaking to me!' wailed Larana, beating her fists against her head. 'What do you want?'

I want to take away your pain if you will but let me. I can make you strong again.

Larana opened her eyes, hope and fear shining in equal measure.

'How? Why?'

I am done with Kroeger. He has descended to the point where his petty slaughters no longer amuse me. But you, oh you have such hate within you! It smoulders, but I see in you the seeds of an inferno. It will be an age before I tire of you, Larana.

Almost against her will, her eyes were drawn towards the gauntlet lying on the dusty floor of the dugout. As if sensing her gaze, the fingers of the gauntlet slowly uncurled so that it lay palm up before her.

Go on! I can feel hate oozing from every pore of your flesh. We shall strike back! He is a butcher of men and deserves to die, does he not? I can help you kill him. Is that not what you desire above all else?

'Yes!' snarled Larana, picking up the heavy gauntlet and slipping her hand inside.

Castellan Leonid rested his elbows on the parapet of the curtain wall and stifled an exhausted yawn as he watched the men on the walls of the two forward bastions with pride. Under the direction of the Imperial Fists, the ramparts had been rebuilt, fresh entrenchments dug at the necks of the bastions and bomb shelters constructed at the base of the walls. The sense of optimism amongst the soldiers was palpable.

He and Captain Eshara stood on the walls beside the towers flanking the Destiny Gate, looking out over the blasted expanse of the plain before the citadel. Craters and thousands of metres of trenches covered the ground, with bodies and wrecked machines left to rot and rust where they lay. Smoke rose in a constant pall from the camp at the end of the valley and seeing the might of the Iron Warriors like this, Leonid wished he shared his soldiers' optimism.

Despite a fearful hammering from the remounted wall guns, the sap driven forward from the partially collapsed second parallel had come to within fifteen metres of the edge of the ditch. A fresh scar on the landscape stretched before them, a third parallel running from the flank of Vin-care bastion to that of Mori bastion.

'It will not be long, will it?' asked Leonid.

'No, not long,' replied Eshara.

'When do you think they will attack?'

'It is difficult to say,' answered Eshara. 'The Iron Warriors never begin an attack until every detail of the assault is in place. There will be a bombardment, feint attacks, diversionary tactics and frontal escalades. Everything will be designed to keep us off balance.'

'I will need you with me when the assault comes, captain.'

'I shall be honoured to fight alongside you.'

'How will they come at us, do you think?'

Eshara considered the question for a moment before replying.

'Without their batteries, it is unlikely that they will try and blast a breach in the walls. All the signs suggest that they will attempt to undermine the walls.'

'They do?'

'Yes. Your forward observers have not reported the construction of batteries, but this parallel is close enough for siege tanks to be deployed behind the earthwork.'

'So why does that suggest the Iron Warriors will be constructing a mine?'

Eshara pointed towards the sap that ran from the second parallel to the third. Plumes of exhaust wreathed the trench in clouds of blue oilsmoke.

'There is an almost constant stream of vehicles travelling back and forth from the forward trench. The trench here is not being widened or extended, yet the earthen rampart they build before it continues to grow. That would suggest that there are mining works being carried out below.'

Leonid swore. He should have noticed that himself. He cursed himself for a fool for not thinking of such a possibility.

'What can we do to stop it?'

'I have begun a series of countermines. One from within a derelict building behind the inner wall and another from within the Primus Ravelin. When they are complete I will fill them with assault troops equipped with auspexes. The troops also have charges for blowing any tunnels they discover and the Adeptus Mechanicus have provided me with an unpleasant surprise for anyone within those tunnels. However, countermining is not an exact science, and we will need to be ready should the Iron Warriors manage to bring down a significant portion of the wall.'

Leonid nodded, watching the activity on the plain with fresh eyes, picturing how the enemy would come at them, and devising counters to meet them.

The citadel's first line of defence was the ditch, six metres deep and thirty wide, in which sat the Primus Ravelin. After crossing the ditch and ravelin, all the while under constant fire from the ramparts, the attackers would have still have to fight their way across the walls.

And if the enemy did manage to carry the walls, then every building within the perimeter of the citadel was a fortress in its own right. From the stores of the Commissariat to the field hospital, each building was equipped with looped windows, armoured entrances, and was capable of offering fire support to those nearby.

But many buildings had taken severe damage already and were continuing to suffer as Arch Magos Amaethon's ability to maintain the shield grew weaker with every passing day.

All the defences needed strengthening, and the men of the Jouran Dragoons worked hand-in-hand with the warriors of the Imperial Fists to make the citadel as impregnable as possible. Eshara and Leonid watched the labours of the soldiers below and were heartened by the sense of shared purpose and camaraderie they saw.

'My compliments, Castellan Leonid, your men do you proud,' observed Eshara, following Leonid's gaze.

'Thank you, captain, we have made fine fellows out of them.'

'Yes, it is a pity that war brings out both the best and worst in men,' sighed Eshara.

'What do you mean?'

'You have seen combat, Castellan Leonid, you know full well the barbarity soldiers are capable of in the fire of battle. But look around you: the bond of brotherhood that has formed here is something that only soldiers facing death can truly know. Every man and woman here understands that they may be dead soon, and yet they are in fine spirits. They have seen the sun rise, but none know whether they will live to see it set. To know that and make peace with it is a rare gift.'

'I don't know that many soldiers would appreciate that.'

'Probably not on a conscious level, no,' agreed Eshara, 'but on a level they may not even be aware of, they do. They fear death, but only by facing it can they truly find their courage.'

Leonid smiled. 'You are a remarkable man, Captain Eshara.'

'No,' said Eshara, without hint of false modesty. 'I am a Space Marine. I have trained my whole life to fight the Emperor's enemies. I have the finest weapons, armour and faith in the galaxy. It is of no matter to me who I fight: I know I shall be triumphant. I say this without arrogance, but there are few foes in this galaxy that can stand before the might of the Adeptus Astartes.'

In any other person, Leonid would have said Eshara's words were arrogant, but he had seen him fight in the battery and knew that the Space Marine captain spoke the truth.

'I know I can defeat any foe,' continued Eshara, 'but your soldiers have no such knowledge, yet still they stand, knowing the enemy is superior to them. They are true heroes and will not fail you.'
