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!"

"That is unfortunate. Your people may yet be saved, Princess Praana. It depends upon Ric Martin."

"What do you mean?" Ric's voice was tight.

Gorak looked at him calculatingly. "You may have wondered why we have revealed everything to you—all of our plans, all of our power. It's because I want you, as an Earthman, to realize what's in store for your planet unless they capitulate. I don't want Earth to go the way of Mars. I don't even want to destroy Earth's moon—unless it's necessary. It's up to you, Ric Martin, to convince your stubborn Earth Council!"

"How can I do that?"

"Tomorrow evening Earth's regular news broadcast will be beamed to Venus. I can cut into the channel again, as I did today. This time you will speak to them. You will tell your Council what you have seen here, and what faces them. It will be their last chance! If you don't convince them ... Luna's destruction will! Earth was aloof when Mars was dying, but this will be much nearer home!"
