Varuz frowned. 'Very well.' He turned his horse, led Jezal and his bodyguard off in the direction of the Arches, down routes that were so familiar, and yet so horribly changed. After a few nervous minutes the Lord Marshal pulled up his mount, pointing down a deserted lane to the west. He spoke softly, as though worried the enemy might hear them.

'Arnault's Wall is no more than three hundred strides that way, and the Gurkish are crawling on the other side. We really should turn—'

Jezal felt a faint vibration through his saddle, his horse started, dust filtered from the roofs of the houses on one side of the street.

He was just opening his mouth to ask what had happened when the air was ripped open by a thunderous noise. A crushing, terrifying wall of sound that left Jezal's ears humming. Men gasped and gaped. The horses milled and kicked, their eyes rolling with fear. Varuz' mount reared up, dumping the old soldier unceremoniously from his saddle.

Jezal paid him no mind, he was too busy urging his own horse keenly in the direction of the blast, seized by an awful curiosity. Small stones had started raining down, pinging from the roofs and clattering into the road like hailstones. A great cloud of brown dust was rising up into the sky to the west.

'Your Majesty!' came Gorst's plaintive cry. 'We should turn back!' But Jezal took no notice.

He rode out into a wide square, a great quantity of rubble scattered across the broken paving, some of it in chunks big as sheds. As the choking dust slowly settled in an eerie silence, Jezal realised that he knew the place. Knew it well. There was a tavern he had used to visit on the north side, but something was changed—it was more open than it had been… his jaw fell. A long stretch of Arnault's Wall had formed the western boundary of the square. Now there was nothing but a yawning crater.

The Gurkish must have dug a mine and filled it with their damned blasting powder. The sun chose that moment to break through the clouds above and Jezal could see all the way across the gaping fissure and into the ruined Arches district. There, crowding at the far edge, clambering down the rubble strewn slope with armour glinting and spears waving, was a sizeable body of Gurkish soldiers.

The first of them were already climbing up out of the crater and into the remains of the shattered square. A few semi-conscious defenders were crawling through the dust, choking and spitting. Others were not moving at all. There was no one to turn the Gurkish back, that Jezal could see. No one but him. He wondered what Harod the Great would have done in this spot.

The answer was not so very hard to find.
