Then she kicked the cask over and scrambled out of the water, a cackle escaping her as, with a flurry of gestures, she opened a warren and plunged into it.

Folding one shadow upon another, Iskaral Pust swiftly traversed a score of leagues. He could half-see, half-sense the desert, buttes and chaotic folds of arroyo and canyon he passed through, but none of it interested him much, until, after almost a full day's travel, he caught sight of five sleek shapes crossing the floor of a valley ahead and to his left.

He halted the mule on the ridge and, eyes narrowing, studied the distant shapes. In the midst of attacking a caravan. 'Arrogant pups,' he muttered, then drove his heels into the mule's flanks. 'Charge, I say! Charge, you fat, waddling bastard!'

The mule trotted down the slope, braying loudly.

The five shapes caught the sound and their heads turned.

As one, the T'rolbarahl shifted direction and now raced towards Iskaral Pust.

The mule's cries rose in pitch.

Spreading out, the D'ivers flowed noiselessly over the ground. Rage and hunger rushed ahead of them in an almost visible bow wave, the power crackling, coruscating between the Shadow warren and the world beyond.

The beasts to either side wheeled out to come in from a flanking position, while the three in the centre staggered their timing, intending to arrive in quick succession.

Iskaral Pust was having trouble focusing on them, so jolted and tossed about was he on the mule's back. When the T'rolbarahl had closed to within thirty paces, the mule suddenly skidded to a halt. And the High Priest of Shadow was thrown forward, lunging over the animal's head.

Head ducking, somersaulting over, then thumping down hard on his back in a spray of gravel and dust.

The first creature reached him, forearms lifting, talons unsheathed as it sailed through the air, then landing on the spot where Iskaral Pust had fallen – only to find him not there. The second and third beasts experienced a moment of confusion as the quarry vanished, then they sensed a presence at their side. Their heads snapped round, but too late, as a wave of sorcery hammered into them. Shadow-wrought power cracked like lightning, and the creatures were batted into the air, leaving in their wakes misty clouds of blood. Writhing, they both struck the ground fifteen paces away, skidding then rolling.

The two flanking D'ivers attacked. And, as Iskaral Pust vanished, they collided, chests reverberating like heavy thunder, teeth and talons raking through hide. Hissing and snarling, they scrambled away from each other.

Reappearing twenty paces behind the T'rolbarahl, Iskaral Pust unleashed another wave of sorcery, watched it strike each of the five beasts in turn, watched blood spray and the bodies tumble away, kicking frenziedly as the magic wove flickering nets about them.

Stones popped and exploded on the ground beneath them, sand shot upward in spear-like geysers, and everywhere there was blood, whipping out in ragged threads.

The T'rolbarahl vanished, fleeing the warren of Shadow out into the world, where they scattered, all thoughts of the caravan gone as panic closed on their throats with invisible hands.

The High Priest of Shadow brushed dust from his clothes, then walked over to where stood the mule. 'Some help you were! We could be hunting each one down right now, but oh no, you're tired of running. Whoever thought mules deserved four legs was an idiot! You are most useless!

Bah!' He paused, then, and lifted a gnarled finger to his wrinkled lips. 'But wait, what if they got really angry? What if they decided to make a fight to the finish? What then? Messy, oh, very messy. No, best leave them for someone else to deal with. I must not get distracted. Imagine, though! Challenging the High Priest of Shadow of all Seven Cities! Dumber than cats, that T'rolbarahl. I am entirely without sympathy.'

He climbed back onto the mule. 'Well, that was fun, wasn't it? Stupid mule. I think we'll have mule for supper tonight, what do you think of that? The ultimate sacrifice is called for, as far as you're concerned, don't you think? Well, who cares what you think? Where to now? Thank the gods at least one of us knows where we're going. That way, mule, and quickly now. Trot, damn you, trot!'

Skirting the caravan, where dogs still barked, Iskaral Pust began shifting shadows once more.

Dusk had arrived in the world beyond when he reached his destination, reining in the plodding mule at the foot of a cliff.

Vultures clambered amongst the tumbled rocks, crowding a fissure but unable or, as yet, unwilling to climb down into it. One edge of that crevasse was stained with dried blood, and among rocks to one side were the remains of a dead beast – devoured to bones and ragged strips by the scavengers, it was nonetheless easy to identify. One of the T' rolbarahl.
