They ran. Behind them, alongside them, and even ahead of them ran wolves, pursuing them across the grassland. Mab was everywhere, sometimes pulling sharply upward, the better to illuminate the way ahead and to spy upon the movements of the wolves, other times diving this way or that to rush into the face of a wolf that had ventured in to nip at Adam’s or Eve’s pounding legs. Behind and around them they could hear the snap of jaws as a beast would rear up to bite the onrushing sprite out of the air, and a whir of wings as Mab dodged the flashing fangs. For all the distraction that Mab provided, it seemed impossible that they would reach the hill before their legs gave out and the wolves took them down. Even were they to reach it, the wolves could climb it as easily as they could.

A heavy thud reverberated through the ground. Then there was another, and another, the pace gradually quickening. Mab, during a brief respite between the attacks of the wolves, swooped up to cast light on the way ahead of them. This ought to have been a featureless sea of grass. But instead there was the hill, so close to them that Mab faltered and recoiled from it. The hill was in the wrong place; it was much steeper than when they had left it; and it was moving.

Mab could not cast enough light to illuminate the whole thing at once, and in any case the impressions of Adam and Eve were confused and fragmentary. But they saw giant stout stumps projecting from its bottom, like legs fashioned from piles of boulders glued together and lubricated by mud, and a midsection that looked like the hill they remembered, and the great tree at the top, looking like a head of stiff hair. The legs took turns moving in a sort of gait that had as much in common with mudslides and avalanches as it did with walking. The thuds they had felt coming up out of the ground were its footfalls. It would have given them pause, had they not been pursued by worse. The wolves faltered and the tone of their voices changed. “Run to it as fast as you can!” Mab urged them. “Whatever the hill-giant does to you cannot be as bad as what these wolves have in mind.”

Adam and Eve put their remaining strength into a last sprint. The hill settled, planting both of its bouldery legs, which collapsed into rock piles that were in the next instant covered and enshrouded by the green skirts of its slopes. Adam was losing his strength but Eve darted ahead and found a way up, and he followed her, just pulling his foot clear of the foremost wolf’s jaws, which snapped harmlessly in the air.
