mighty motivations there crept in an overmastering need for, and the exact method of obtainment of, whatever it was that was each Velantian's deepest, most primal desire. Each crewman stared into an individual visiplate whose substance was to him as real and as solid as the metal of his ship had ever been; each saw upon that plate whatever it was that, consciously or unconsciously, he wanted to see. Noble or base, lofty or low, intellectual or physical, spiritual or carnal, it made no difference to the Overlords. Whatever each victim most wanted was there.

No figment was, however, even to the Velantians, actual or tangible. It was a picture upon a plate, transmitted from a well-defined point in space. There, upon that planet, was the actuality, eagerly awaited; toward and to that planet must the Velan go at maximum blast. Into that line and at that blast, then, the pilots set their vessel without orders, and each of the crew saw upon his nonexistent plate that she had so been set. If she had not been, if the pilots had been able to offer any resistance, the crew would have slaughtered them out of hand. As it was, all was well.

And Worsel, watching the affected portion of his mind accept these hallucinations as truths and admiring unreservedly the consummate artistry with which the work was being done, was well content. He knew that only a hard, solidly-driven, individually probing beam could force him to reveal the fact that a portion of his mind and all of his bodily control were being withheld; he knew that unless he made a slip no such investigation was to be expected. He would not slip.

No human or near-human mind can really understand how the mind of a Velantian works. A Tellurian can, by dint of training, learn to do two or more unrelated things simultaneously. But neither is done very well and both must be more or less routine in nature. To perform any original or difficult operation successfully he must concentrate upon it, and he can concentrate upon only one thing at a time. A Velantian, however, can and does concentrate upon half-a-dozen totally unrelated things at once; and, with his multiplicity of arms, hands, and eyes, he can perform simultaneously an astonishing number of completely independent operations.

The Velantian is, however, in no sense such a multiple personality as would exist if six or eight human heads were mounted upon one body. There is no joint tenancy about it. There is only one ego permeating all those pseudoindependent compartments; no contradictory orders are, or ordinarily can be, sent along the bundled nerves of the spinal
