Bart nodded. "Meet you on the upper level later," he said, and got on a moving staircase that soared slowly upward, past level after level, toward the information desk located on the topmost mezzanine.

The staircase moved slowly, and Bart had plenty of time to see everything. On the step immediately in front of him, two Lhari were standing; with their backs turned, they might almost have been men. Unusually tall, unusually thin, but men. Then Bart amended that mentally. The Lhari had two arms, two legs and a head apiece—they were that much like men. Their faces had two eyes, two ears, and a nose and mouth, all in the right places. But the similarity ended there.

They had skin of a curious pale silvery gray, and pale, pure-white hair rising in what looked like a feathery crest. The eyes were long and slanting, the forehead high and narrow, the nose delicately thin and chiseled with long vertically slit nostrils, the ears long, pointed and lobeless. The mouth looked almost human, though the chin was abnormally pointed. The hands would almost have passed inspection as human hands—except for the long, triangular nails curved over the fingertips like the claws of a cat. They wore skin-tight clothes of some metallic silky stuff, and long flowing gleaming silvery capes. They looked unearthly, elfin and strange, and in their own way they were beautiful.
