She looked down at the craft, studying lines which had become familiar to her in weeks of designing, building and testing. Hork V had decided to call his extraordinary craft the "Flying Pig." It was a clumsy, ugly name, Dura thought; but it caught the essence, maybe, of a clumsy, ugly vessel. The ship as finally constructed — after two failed prototypes — was a squat cylinder two mansheights across and perhaps three tall. The hull, of polished wood, was punctured by large, staring windows of clearwood. There were also clearwood panels set into the upper and lower cross-sections of the cylinder. The whole craft was bound about by five hoops of sturdy Core-matter. The Air-pigs whose farts would power the vessel could be seen through the windows, lumps of straining, harnessed energy. The ship was suspended by thick cables from huge, splintered pulleys which — on normal days — bore Bells down toward the Quantum Sea.

This, then, was the craft which would carry two people into the lethal depths of the underMantle. In the dingy, dense Air of the City's Harbor the thing looked sturdy enough, Dura supposed, but she doubted she'd feel so secure once they were underway.

There was a disturbance above her, a sound of hatches banging. Hork V, Chair of Parz City, resplendent in a glittering coverall, descended from the gloom above. He seemed to glow; his bearded face was split by a huge smile. Dura saw that Physician Muub and the engineer Seciv Trop followed him. "Good day, good day," Hork called to Dura, and he clapped her meatily on the shoulder-blade. "Ready for the off?"

Dura, her head full of her regrets and fears, turned away without speaking.

Seciv Trop wafted down, coming to rest close to her. He touched her arm, gently; the many pockets of his coverall were crammed, as usual, with unidentifiable — and probably irrelevant — items. "Travel safely," he said.

She turned, at first irritated; but there was genuine sympathy in his finely drawn face. "Thanks," she said slowly.

He nodded. "I understand how you're feeling. Does that surprise you? — crusty old Seciv, good for nothing without his styli and tables. But I'm human, just the same. You're afraid of the journey ahead..."

"Terrified would be a better word."

He grimaced. "Then at least you're sane. You're already missing your family and friends. And you probably don't expect to make it back, ever."

She felt a small surge of gratitude to Seciv; this was the first time anyone had actually voiced her most obvious fear. "No, frankly."

"But you're going anyway." He smiled. "You put the safety of the world ahead of your own."

"No," she snapped. "I put my brother's safety ahead of my own."

"That's more than sufficient."
