Denser blew out his cheeks. 'Sort of. Bringing the Al-Arynaar to Julatsa to raise the Heart was something Ilkar wanted to do. It's why we went to Calaius in the first place, before the Elfsorrow struck. As for this failure of Julatsan magic, I don't know. Like Erienne says, this goes against all our teaching. Burying a Heart will stop development because the core power can't flow and that's why you'd only bury one if it would otherwise be destroyed.'

'Which is what Julatsa did when the Wesmen invaded.'

'Exactly, Hirad. But it should still beat. The power should never falter. There's no reason why, that's what we don't understand.'

'So we get the Al-Arynaar mages and go to Julatsa. What are we waiting for?' Hirad spread his hands.

'Hirad, please,' said The Unknown. ‘Iknow you're anxious but we have to do this right. Where's Rebraal?'

'I am here.' Ilkar's brother, leader of the Al-Arynaar, walked from the shadows where he'd been leaning against a tree.

'We need to talk to one of your mages. Well, Erienne and Denser do. Find out what timescale we're dealing with here.'

Rebraal nodded. 'Of course. Our lead mage is Dila'heth. I'll bring her to you.'

'Thank you. Now, Izack, what have you been told about us?'

'The official line is that you're outlaws and General Darrick is a condemned man wanted for his execution. But it doesn't add up. We are told not to harm any of you but to bring you back to Lystern alive and well. And the Dordovans have been told the same thing.' Izack smiled. 'Heryst and Vuldaroq may dislike each other but we fight side by side. We're friends, mostly, and we talk.' The smile faded. 'But everyone here knows there's more to it. Unknown, every mage here felt the casting. The elves rejoiced, Lysternans and Dordovans were troubled. And everyone knows the timing of the casting and your escape from Lystern. It's too coincidental.' Izack looked square at Erienne. 'People have drawn their own conclusions. That's why you have to be so careful.'

'And what about you?' asked Erienne, meeting his gaze.

'The General believes in you so I believe in you too.'

Erienne said nothing but raised her eyebrows a fraction in acknowledgement. Denser put a hand on her knee and she returned her gaze to the fire.

'So tell me, have the TaiGethen completed their scouting?' asked The Unknown.

'Yes,' said Izack. 'But I think they're still worried about how to get into the college itself

'That's where we come in,' said Denser. 'Or more particularly, where I come in.'

'You're planning on going in with them?'

'Think we're safer out here among our allies, Izack?' said Hirad.

'Surely in the elven camps-' he began.

'We've business to attend to,' said The Unknown. 'And we're not sitting out here hiding our faces and watching the action.'

‘Itake your point,' said Izack.

'One more thing, Commander,' said The Unknown. 'Just how would this front hold up if the elves were to leave it?'

'Simple. It wouldn't.' Izack shrugged.

'You do know that once we've finished inside Xetesk, the elves won't stay here,' said The Unknown.

‘Iam well aware of their reasons for joining our fight thus far,' said Izack shortly.

'Then you have to be ready for them to leave – mostly to march north to Julatsa to help raise the Heart.'

'Then the siege of Xetesk will collapse. They can rout us from the east gate at will, and every other front will be compromised as a result.' Izack sighed heavily. 'They know why we're fighting this war. They will benefit from our victory. Gods, I've fought so hard to establish what we have and lost so many doing it. Don't leave us defenceless. You'll be handing the victory to Xetesk.'

'Want to know what I think?'

'About war, Darrick, absolutely everything,' said The Unknown.

Rebraal and an exhausted-looking elven woman who had to be Dila'heth, walked into the camp. The Unknown pointed them at Denser and Erienne and, after brief introductions, the four engaged in fervent conversation.

'The moment we retrieve the elven writings, as we must, keeping us at bay will become unimportant to them. Surely they are doing nothing more than keeping us from the walls because they are researching what they have learned from the Al-Drechar and those same writings,' said Darrick.

'Well, I like to think our forces are keeping them from surging north to destroy Julatsa, which I take to be their first goal,' said Izack.

'Let me ask you something, Izack,' said Darrick, now every inch the general of the armies. The position in which he so excelled. 'What is the purpose of your engaging the Xeteskians in this combat?'

'To probe for that weak point. To try and make the breakthrough. Turn the battle in our favour.'

'Wrong. That is the Dordovan command holding sway over you, if that is what you really believe.'

Hirad leaned forward, rapt despite his tiredness.

Izack stared at the floor. 'We have to beat them,' he said. 'Time is short. I've always known the elves would leave one day.'

'In a siege you're just wearing them down,' said Darrick. 'Bit by bit. Otherwise, why engage them at all? Why risk your own men? What you have to believe is that they will crack under the pressure, living in the prison you have created for them. This siege is being fought just as much in the mind as it is on the battlefield.

'Now your defeat the other day was damaging. It allows Xetesk to rest because you can't afford to fight them on this front. If he's clever, Dystran will be making sure his generals are rotating duty on all fronts now.

'His men are fresh out there in front of you, aren't they?'

Izack nodded, mute, sucking in his top lip.

'You won't break them,' said Darrick. 'That isn't where we will beat Xetesk. Whatever Vuldaroq and Heryst believe, we can't win here.'

'So what the hell am I doing!' Izack bit down on his temper. 'General?'

'You're showing them we won't be beaten and you have bought us and the elves the time we need. You've weakened them, make no mistake. And when we get out of Xetesk with the writings, having done whatever damage we can to their research, they are going to come after us. And not just because of a few ancient texts.'

'How so?' asked Hirad.

'There is more they will want. The power of the One, which they surely crave will be lost unless they break the siege. And if the Al-Arynaar succeed and raise the Heart of Julatsa and we can protect it while it strengthens, they will be on the brink of losing the war.' Darrick raised his eyebrows.

'And what makes you so sure they can break the siege?' asked The Unknown.

'They're keeping plenty in reserve, I can feel it,' Darrick said. 'They have made no move to break out because they don't need to. Not yet. But mark my words, they will be mobilising for a move north soon. If they start to push at all four gates you'll know it's imminent because they'll be striving to occupy every enemy they can. What we can do by getting in and out of Xetesk is force their hand. We don't want them ready, believe me.'

'So what do we do?' asked Izack. 'How do we stop them?'

'Now's the time.to be fighting harder than you ever have at every gate. Every one of them that dies or is forced to fight until exhaustion is a victory. I know we'll suffer losses too but we'll have the psychological edge. And when they try to break through the north gate as they will, we need to have enough men and mages in reserve to chase them. Don't forget, we can't abandon the siege or we'll be just inviting more Xeteskian warriors to chase up to Julatsa. We cannot allow them to know we are reinforcing the north gate lines. We must make them fight to keep their city even while they run to attack Julatsa and reclaim the writings and, if they're lucky, Erienne, when they guess her identity.'

'But that's the trick, though, isn't it?' said Izack wearily. 'How do we manage our resources to manufacture a meaningful reserve? How can we take most of our men from the fight east, south and west and still keep the pressure up on Xetesk?'
