She placed both hands on the wall, and summoned her own creatures. They would bypass the protections on this place—one great fault Air Masters often had was that they forgot that things could come up from below as well as down from above. Their protections tended to be domes rather than spheres. Water Masters and Fire Masters rarely made that mistake.
Up they came, slow and cold, investing the walls and the floor with their presence, swimming through the stone as an undine would swim through water. Kobolds and tommyknockers, mostly, those creatures that invested rock rather than earth, and who hated mankind with an enduring passion as the invader and despoiler of their secret underground fastnesses. They had the power to bring down mines when angered, and the only reason that they weren't more dangerous than trolls and giants was that they were slow to work on their own, and solitary, and found it difficult to work with one another.
She bound them with spell and command, it wasn't difficult, given what she intended them to do. They hated mankind in general, and Air Magicians worst of all. Ah, the benefit of working against a Master of the inimical Elemental; it was seldom that she commanded any of her creatures under these circumstances that was not pleased to do her will.
The spell was set, the trap laid, and there was no point in remaining. The Air Master would be returning soon. He would check his boundaries and find them untouched, because her invaders had not forced, had not even crossed them. Only when the clock crossed into the dark side of the night, at just past midnight, would her minions—"strike" was not the correct word, for they would approach by stealth. "Envelop" was more accurate. As he slept, they would creep upon him, imprison him, paralyze him. And then, they would slowly, so slowly, squeeze the breath out of him, sitting on his chest while he struggled for air, until the lungs collapsed and the laboring heart gave out. There would be no sign that he had died of anything other than natural causes.
This was far superior to invoking a were-creature and tearing her victim apart, which is what she had been forced to do the last time. Stealth was always preferable to direct conflict. Whenever she could avoid a mage-battle, she felt that she had won two victories in one.
She sauntered back to the waiting automobile, feeling altogether pleased with herself. The amount of terror and pain that this particular murder would produce would be remarkable, and that in turn, would enrich the power given up at the death. The victim might well last most of the night. The kobolds would absorb that power—retain some for themselves—but deliver the lion's share to her.
Which would, in turn, give her more power for the conquest of Reginald Fenyx. She would need extra power; Earth Elementals had already feasted on his fear and pain, and would hunger for more. If she had meant to destroy him, that would have been fine, but she would need all her magic and cunning to keep them restrained and held in check.
She drove back home in the sunset; the auto was constructed of enough of the materials of Earth—though it was powered by Fire and Air—that it did not dare misbehave under her hand. Which was more than could be said of horses, or, for that matter, any other living beast that she hadn't specifically bred, altered, and trained. That was the drawback to being a Dark Master; animals didn't much care for you.
Well, the antipathy was mutual.
She brought it to a halt inside what had been the stable, and turned it off as the last light of the day slowly faded. Through the garden door she came, walking briskly up the path as light shown warmly through the kitchen windows.
Of course, she did not have to go through the kitchen, for there were two doors into the garden—the kitchen door and this one. It would never do for
She went upstairs to clean herself from the drive, and smiled at herself in the mirror. It had been a most satisfactory day.
