'Come on, Uriel,' he hissed. 'Where are you?'
At the sound of the first explosion, Jenna Sharben leapt into action. Her burst of movement caught Koudelkar's eye, and he watched in horror as she spun her crutch around and stabbed it into the belly of one of Aun'rai's bodyguards. Only then did he notice that the bottom of each crutch had been sharpened to a lethal point.
The Fire Warrior screamed foully and collapsed, blood pouring down his legs from the terrible wound. Clearly the chief of enforcers was not as debilitated by her wounds as she had led the tau to believe.
Sharben swung her other crutch around in a short, brutal arc, the heavy end hammering into another bodyguard's helmet with a solid crunch. The warrior went down heavily as Sharben turned to face the last of Aun'rai's protectors.
Koudelkar made to go to Aun'rai's aid, but his mother gripped his tunic tightly. Her eyes pleaded with him not to go, but, for better or worse, Koudelkar had made his choice, and he had to live up to his end of the bargain.
He threw off her grip, though it broke his heart to hear her despairing cry.
'Koudelkar, no!' shouted Perjed. 'Don't.'
Though Sharben had fooled them with her display of weakness, the element of surprise could only see her so far, and La'tyen leapt on her with an anguished cry of hatred. Arbites Judge and Fire Warrior rolled on the ground, punching and clawing at one another.
The chief enforcer's elbow slammed into La'tyen's midriff, but the Fire Warrior's flexible body armour bore the brunt of the blow. La'tyen hooked her arm around Sharben's throat and dug her fingers into her neck. Sharben slammed her head backwards into La'tyen's face, and Koudelkar heard the crack of a cheekbone breaking. Sharben rolled from her opponent with a grunt of pain, scrabbling for a weapon as La'tyen drew a glittering knife from her belt.
Koudelkar had heard that they were called honour blades, and were ceremonial weapons used to symbolise fraternity amongst the tau, though there was nothing ceremonial about its viciously sharp edge.
The blade slashed towards Sharben, who leapt back to avoid being gutted. She cried out in pain as her weight came down on her injured leg. The Arbites Judge was not as badly hurt as she had made out, but she was still hurt.
Koudelkar wanted to intervene, but knew La'tyen would as likely gut him as Sharben. The bleeding Fire Warrior continued to cry out in pain as his blood spilled from his wound, but his dazed compatriot was rising unsteadily to his feet with a rifle held before him.
La'tyen feinted with her honour blade, and Sharben fell to one knee as her wounded leg gave out beneath her. It was the opening that La'tyen needed, and she plunged the blade of her knife into Sharben's chest.
The combatants crashed to the floor, and La'tyen stabbed the mortally wounded enforcer again and again in a frenzy of grief, anger and hatred. Blood spurted, and sprayed the walls in spattering arcs as La'tyen let the horror of her torture in the Glasshouse pour from her in a frenzy of savage violence.
Koudelkar recoiled from the awfulness of Sharben's death, horrified at the animal savagery of the killing. La'tyen looked up, and through the mask of blood coating her twisted features, Koudelkar saw the true nature of the tau race, the darkness they kept hidden behind their veneer of civilisation and fantastical notions of the Greater Good.
Lortuen Perjed ran forwards as Sharben died, desperation lending his aged limbs strength. He bent to retrieve the short-barrelled weapon dropped by the Fire Warrior Sharben had first attacked, and fumbled with the firing mechanism.
'Don't be an idiot, Lortuen! Put the gun down!' shouted Koudelkar, having no wish to see Lortuen killed in this terrible folly. The adept was not to be dissuaded from his course, however, and he and the dazed Fire Warrior pulled the triggers in the same moment. Koudelkar flinched as volleys of searing blue energy beams sprayed the room.
The Fire Warrior went down in a crumpled heap, his chest a cratered ruin, but he had taken his killer with him. Lortuen Perjed was punched from his feet, his fragile body torn virtually in two by the flurry of high energy bolts.
As terrible as was Lortuen's fate, the true horror was behind the murdered adept.
Koudelkar's mother slid down the pristine walls of his quarters, leaving a bloody smear behind her. Pawluk Shonai's eyes were wide with pain, and her prison-issue tunic was soaked with an expanding red stain.
'No!' cried Koudelkar, running over to his mother. He gathered her up in his arms as tears blurred his vision. He put his hand on her stomach, trying in vain to stem the flow of blood from her body.
'Emperor save her, please, oh please no!' wailed Koudelkar, desperately pleading with the only god he knew to save his mother. 'Oh God-Emperor, no, don't let this happen!'
Koudelkar watched the life drain from his mother's eyes, and gave a terrible, aching cry of loss. His eyes filled with tears, and he sobbed as he held her lifeless body tight.
'I'm sorry, I'm sorry,' he wept. 'It's all my fault. I betrayed you, oh Emperor forgive me, please forgive me…'
Koudelkar felt a presence near him, and looked up from his grief to see Aun'rai standing over him, his expression one of profound disappointment.
'You call to your Emperor for aid?' asked Aun'rai. 'After all we have discussed, you still turn to your distant Emperor for solace? No matter what your intellect might say, you look to gods and spirits in times of trouble. How pathetically human of you.'
'She's dead!' wailed Koudelkar. 'Don't you understand? She's dead.'
'I understand all too well,' said Aun'rai coldly, as La'tyen appeared at his side, her face and armour drenched in Sharben's blood.
Koudelkar fought to cling onto his sanity in the face of this horrific bloodshed. In a matter of seconds, his bright future of importance and luxury had turned to horror and grief. He shook his head, and gently laid his mother down on the cold, hard floor of his quarters.
He stood and faced the two tau. One desperately wanted to kill him, the other to enslave him, and Koudelkar wasn't sure which fate he dreaded more.
'It does not have to end here,' said Aun'rai. 'You can still be part of the Greater Good.'
'I think not,' replied Koudelkar, backing out of the doorway, through which the crack of gunfire and the boom of explosions could be heard. 'I want nothing from you or your race. If I am to die, then I will die among my own kind.'
Koudelkar turned and walked down the steps to the landing platform. He could taste the smoke in the air and the crackling electric charge of the downed security fences. Shouting soldiers and the bark of weapons' fire surrounded him, but Koudelkar had never felt more at ease with himself.
He remembered a conversation he'd had with Lortuen Perjed not long after they had arrived at the prison camp.
'We are prisoners of war,' Koudelkar had said. 'What honour do we have?'
'Only what we bring with us,' was Perjed's reply, and only now did Koudelkar understand what the adept had meant. He lifted his head and looked into the achingly blue sky, taking a deep breath of the ocean-scented air.
Koudelkar frowned, and raised a hand to shield his eyes from the sun as he saw a number of falling objects that looked out of place in the heavens. He smiled as he recognised them for what they were.
Aun'rai appeared in the doorway of his quarters, seemingly unconcerned with the fighting that raged through the prison complex.
'This foolish uprising will be quashed,' spat the tau. 'And nothing will have changed.'
'You know, I think you're wrong about that,' said Koudelkar, pointing towards the sky where a host of Space Marine drop-pods streaked towards the ground on blazing lines of fire.
