The keep was supposed to be held by nothing more formidable than an old man and a handful of retainers. Certainly the Guard was days away at the best forced march pace, though that shouldn't have mattered. Because no one was supposed to know that the keep was held so weakly. And no one was supposed to know that it guarded a very strategic supply route.
But someone did know; someone had been leaking information to the Karsites. Poorly-guarded keeps of strategic importance behind the Valdemar lines were being decimated, the occupants slaughtered, leaving holes the strategists didn't learn about until it was too late. Or worse w en the strategists checked on their supposed holdings, they found keeps somehow occupied by hostile forces.
Vanyel read the signs of magic, and had known only magic could counter these attacks. So Vanyel had ridden Yfandes to exhaustion to reach this one, a likely target. He'd cleared out the old man and his following, and waited.
And the attack had come, in the form of a gretshke-Swarm; demi-demonic creatures (mostly head, teeth, and appetite) that, taken individually, were inconsequential. An ordinary fighter could deal with one - or two; and they certainly were not immune to cold iron. But a Swarm - that was another matter. The Swarm contained hundreds, if not thousands, of the creatures. You could kill them by the dozens, and still they would overwhelm you, like encountering an avalanche of starving rats.
A mage didn't control a Swarm; he just unleashed it. When the food was gone, or when they were sated, they would return to their own plane if they were given an exit. So a mage using them would customarily lure a Swarm to the Portal to their plane that he had opened within his target area and cast a shield about the target to keep the Swarm from escaping. He would wait an appropriate length of time - usually no more than a candlemark; the Swarm was fast - and open the Portal again to pull whatever of the Swarm remained back to their own plane. He would take the shield down then, and an occupying force could move in.
All this required someone on the level of Adept; which made it likely that the mage in question was one of the three Adepts the Karsites had hired when they began this. One of the three had threatened, then launched the brutal incineration of an entire town; the town had been saved, but in stopping him Mardic and Donni had called the flames on themselves in a desperate attempt to confine them.
It had worked. It had been a brave, unselfish-and ultimately fatal - ploy. The best that could be said was that their pain had been mercifully short.
Vanyel had been determined that before he was pulled off the lines, he would have that particular mage's life. By preference, given the other things they'd done, he would have all three, but he wanted that one.
The only problem was, the mages themselves refused confrontation; striking time and time again where he wasn't. By the time of this ambush he'd had enough. He had begun hunting them with the patience and stealth that would eventually earn him the name “Shadowstalker” when he tracked down the second Adept.
But that was in the future; at that moment, the first step on his self-appointed road of revenge, he had been waiting in the darkened keep, fueling the delicate illusion that made it appear to that unknown enemy that only the old man and his dozen retainers and fighters were within those walls, and all were asleep. He felt the shields go up; he felt the portal open. The Swarm descended on the Hall of the keep, where he waited for them beside the firepit in the center. And he threw up his own shield, abandoning the illusion, and watched as the Swarm ravened outside it, tearing the scant furnishings of the Hall to shreds in frustration, unable to reach the meat so tantalizingly out of reach.
While he smiled grimly and set up a second shield between the Swarm and the portal. When the mage opened the Portal again, then established a probe to check on the results of his work, Vanyel would seize on the probe before he could withdraw it, and use it to send him an unexpected surprise.
It was the image of the Swarm shredding cushions, furnishings, and tapestries that interested him now; an image he sent swiftly to Savil, who seized on it with an exclamation. Jervis raised his eyebrow.
“We think we may have an explanation for all the destruction," Vanyel explained absently, as he and Savil conferred in Mindspeech. "It's complicated, and there's a lot of 'ifs' and 'buts.' It may take us a while to unravel them, but the explanation fits the current evidence."
Jervis just shook his head. "If that's magery, then it's too much for me, Van," he said, yawning. "I'll leave that to you. I'll just show you that room and let you deal with it, eh?"
"I'll do that," Vanyel replied, then turned his mind to looking for the traces that would tell him what kind of things had torn the hall to shreds-because that would tell him a great deal about how strong the enemy was - and importantly, might even give a clue as to who.
But in the end, he and Savil sought their beds without any answers but one. How strong was very. Adept at least.
Because the traces that would have distinguished what the trap-spell had unleashed had been skillfully wiped away. All that remained was the heavily camouflaged spell itself (which only an Adept could have detected under the camouflage) and the bare traces of magic that had alerted them in the first place.
Jervis and Tashir were already asleep when they gave up.
"Sleep?" he asked Savil, hoping she'd answer in the affirmative.
"We might as well. We aren't going to get anything more tonight." She stretched once, and began burrowing into her blankets, practically radiating exhaustion. Vanyel realized then what kind of strain she was under - all this complicated, involved sorcery, and maintaining her position as the Web's Eastern Guardian. He resolved to take more of the burden from her as soon as he could. This was not fair to her, nor was it good for her.
I wonder if there's a way to tie all the Heralds into the Web, as power-source at least. That would take fully half the burden off the Guardians.
"Want me to put out the candles?" he asked, glancing around at the burning tapers still bedecking corners of the kitchen.
She opened one eye thoughtfully. "No. Just leave them, if you would. It isn't as if we need to hoard them, and I don't think I want to go to sleep in darkness for a while."
Vanyel thought it over a moment, and nodded. "You know what, teacher-mine?" he said softly. "Neither do I."
She chuckled wearily, and closed her eyes again. "Absurd, isn't it? Here we are, two of the ranking Herald-Mages in Valdemar - afraid of the dark.''
He wrapped himself up in his own blankets. "If you promise not to tell anyone, I won't either."
A light snore was his only answer, and he fell asleep with the comforting glow of the candles all about them.
