The captor Tennant called Opal came in through a far corner of the ceiling. He—if it was a he—was not large, although this, Tennant knew, meant nothing; Opal might extend thousands of yards in some unseen direction. He had no regular shape and much of him was iridescent and shot with constantly changing colors. Hence the name Opal.
Communication was telepathic. Tennant could have yodeled or yelled or sung Mississippi Mud and Opal would have shown no reaction. Yet Tennant suspected that the captors could hear somewhere along the auditory scale, just as perhaps they could smell, although not in any human sense.
You will approach without use of your appendages.
The command was as clear as if it had been spoken aloud. Tennant took a deep breath. He thought of the space beside Opal. It took about three seconds and he was there, having spanned a distance of some ninety feet. He was getting good at it.
Dog does trick, he thought.
He went through the entire routine at Opal's bidding. When at last he was allowed to relax, he wondered, not for the first time, if he weren't mastering some of the alleged Guru arts. At once he felt probing investigation. Opal, like the rest of the captors, was as curious as a cat—or a human being.
