It was perhaps a week later that Kueelo came to them, after the days work. "Gorak wishes to see you. All of you!" Tal and Praana were puzzled. In Ric, a spark struck home. He struggled to rouse himself. Gorak ... what could he want with them now? * * * * * "Today," Gorak told them when they appeared in his quarters, "I spoke with the Earth Council. I gave them my ultimatum." He paused, watching their amazement. Then he turned to the tele-magnum, a huge and magnificent instrument, as powerful as anything Earth had. "I cut into the Earth beam while they were broadcasting to Venus and, by drowning out their channel, contacted them for a few minutes. Needless to say," he turned his cold orbs upon Ric, "they refused my terms. They refuse to believe I destroyed Mars. Of course I realize it would be hard for them to capitulate even if they wanted to. Earth's Fleet is divided, and all has not gone well with Wessell. Already there have been skirmishes around Luna, and part of Wessell's fleet has gone down to destruction." Ric's heart leaped. At least this was good news! But Gorak's cold voice went on. "I cannot wait for them to destroy themselves, because in two more days Phobos comes into juxtaposition with Earth, and that will not happen again for months. Earth must have an object lesson! Come. I wish to show you what I mean." Once again they entered the atomo-car and were speeding away from the city, traversing Phobos' inner shell. They passed the laboratories and shops, hearing the clangor of work still going on. They came to a place where huge, powerful-looking rockets were arranged in neat rows. There were literally hundreds of them. "Those are the bombs!" Tal whispered to Ric. "They explode upon contact, releasing the spores!" Their car had stopped, and Gorak ordered them out. Kueelo and Naric were there, and dozens of Phobians, fully armed. The place was well guarded. They saw vast mechanisms reaching endlessly across the wall. These were topped by huge metal discs, perhaps ten feet in diameter. "The propulsion pits," Gorak explained. "Even vaster, of course, than those we used against Mars. I wanted you especially to see these--Ric Martin. Kueelo, show him." Kueelo stepped to the operating board. Slowly, under his control, one of the huge discs slid back. A great, gleaming metal bore was revealed. It ejected toward them silently, as though on great compression coils. "The bores extend entirely through Phobos' shell," Gorak went on. "It has been the work of years. They rest on huge pivots and can be adjusted to any desired angle." He waved a hand. "As you can see, we have twenty of them. Let us hope we will not need them all. Luna is airless, and the action of the spores will be faster there than on Mars." "Luna!" Praana swayed and would have collapsed, but for Tal Horan's arms about her. "You're going to land the spores on Earth's moon? My people are there ... bottled up in Tycho!"
