"Brother, I'm way ahead of you!" Cooms said. His expression hardened. "That doesn't look good. But at least he can't bring in reinforcements without tipping us off. We've got our own guards down with theirs at the entrance."

Quillan gave him a glance, then nodded at the wall beyond them. "That's a portal over there, Marras. How many of them on this level?"

"Three or four. Why? The outportals have been plugged, man! Sealed off. Fluel checked them over when we moved in."

"Sure they're sealed." Quillan stood up, went to the portal, stood looking at the panel beside it a moment, then pressed on it here and there, and removed it. "Come over here, friend. I suppose portal work's been out of your line. I'll show you how fast a thing like that can get unplugged!" He slid a pocketbook-sized tool kit out of his belt, snapped it open. About a minute later, the lifeless VACANT sign above the portal flickered twice, then acquired a steady white glow.

"Portal in operation," Quillan announced. "I'll seal it off again now. But that should give you the idea."

Cooms' tongue flicked over his lips. "Could somebody portal through to this level from the Star while the exits are sealed here?"

"If the mechanisms have been set for that purpose, the portals can be opened again at any time from the Star side. The Duke's an engineer of sorts, isn't he? Let him check on it. He should have been thinking of the point himself, as far as that goes. Anyway, Velladon can bring in as many men as he likes to his own level without using the main entrance." He considered. "I didn't see anything to indicate that he's started doing it—"

Marras Cooms shrugged irritably. "That means nothing! It would be easy enough to keep half a hundred men hidden away on any of the lower levels."

"I suppose that's right. Well, if the commodore intends to play rough, you should have some warning anyway."

"What kind of warning?"
