Dura hurried to obey, skirting the hovering pig.

With a howl that rent the glutinous Air, the pig charged Adda.

Adda twisted in the Air and began to Wave out of the way, his legs thrashing at the Magfield...

But, Dura saw instantly, not fast enough.

Clinging to the weeping Farr there was nothing she could do as the final, ghastly moments unfolded. Adda's face showed no fear — but no acceptance either, Dura saw; there was only a grimace of irritation, perhaps at this newest failure of his crumbling body.

As it closed on Adda, trailing green clouds of jetfarts, the sow opened its mouth.

The huge, circular maw closed on both Adda's legs. The momentum of the hurtling sow carried away both pig and Adda, and Dura cried out as she saw Adda's fragile body smashed against a tree trunk. But he was still conscious, and fighting; with both fists he pounded on the sow's wide, quivering back.

Dura kicked away from the tree and Waved as hard as she could toward the pig. Philas was approaching the pig from the far side, her stabbing spears held out before her. The woman's eyes were wide, emptied by shock and terror.

The pig, halted by its impact with the tree, pulled back into clear Air now, and it began, with lateral squirts of gas, to rotate around its long axis. Adda seemed to realize what was happening. With his legs still trapped, he beat harder at the pig's flank, cursing violently. But still the pig twisted, ever faster, becoming at last a blur of fins and eyestalks. Jetfart gas trailed around its body in circular ribbons, and electron glow sparkled from its fins. Adda, at last, fell backward and lay against the pig's long flank, his knees bent cruelly.

This was the way boars killed their prey, Dura knew: the boar would spin so fast that the superfluidity of the Air which sustained all animals in the Mantle, including humans, broke down. It was simple, but deadly effective. Even now, she knew, the pain of Adda's trapped legs, the agony induced by the whirling of the world around him, would be subsumed by a dull, disabling numbness as his muscles ceased to function, his senses dimmed, and at last even his mind failed.

With a yell from deep in her gut, Dura threw herself at the whirling animal. She scrabbled at its smooth, slippery hide, feeling her belly and legs brush against its hot flesh. She stabbed at its tough epidermis once, twice, before being hurled clear. She tumbled backward through the Air, colliding with a trunk hard enough to knock the breath out of her.
