L2 Worsel, then, held himself aloof and observed appreciatively everything that went on. More, he did a little hallucinating of his own. Under the Overlords' compulsion he was supposed to remain motionless, staring raptly into an imaginary visiplate at an orgiastic saturnalia designed to make even his burly ego quail. Therefore, as far as the occupied portion of his mind and through it the Overlords were concerned, he did so. Actually, however, his body moved purposefully about, under the direction only of his own grim will; moved to make ready against the time of landing. For Worsel knew that his opponents were not fools. He knew that they reduced their risks to the irreducible minimum. He knew that the mighty _Velan_, with her prodigious weaponry, would not be permitted to be within even extreme range of the cavern, if the Overlords could possibly prevent it, when that cavern's location was revealed. His was the task to see to it that she was not only within range, but was at the very portal. * * * * * The speeding spaceship approached the planet--went inert--matched the planetary intrinsic--landed. Her air locks opened. Her crew rushed out headlong, sprang into the air, and arrowed away _en masse_. Then Worsel, Grand Master of Hallucinations, went blithely but intensely to work. Thus, although he stayed at the _Velan's_ control board instead of joining the glamoured Velantians in their rush over the unfamiliar terrain, and although the huge spaceship lifted lightly into the air and followed them, neither the fiend-possessed part of Worsel's mind, nor any of his fellows, nor through them the many Overlords, knew that either of those two things was happening. To that part of his mind Worsel's body was, under full control, flying along upon tireless wings in the midst of the crowd; to it and to all of the other Velantians and hence to the Overlords the _Velan_ lay motionless and deserted upon the rocks far below and behind them. They watched the vessel diminish in apparent size in the distance; they saw it vanish beyond the horizon! This was eminently tricky work, necessitating as it did such nicety of synchronization with the Delgonian's own compulsions as to be indetectable even to the monsters themselves. Worsel was, however, an expert, one of the Universe's best; he went at the task not with any doubt whatever as to his ability to carry it through, but only with an uncontrollably shivering physical urge to come to grips with the hereditary enemies of his race.
