"No," Skulduggery agreed, "we don't. Something tells me they'll be a tad angry with you."

The chalk symbols closest to the cave entrance were glowing. Skulduggery had no idea if that was meant to happen or not, but as Gabe said, there was no reason to stick around and find out. He turned and led the way deeper down the tunnel, moving confidently forward as the air ahead remained clear of any movement.

"How does this work?" Skulduggery asked after a moment of silence slid by. "Will I be able to feel it?" He could always handle pain, but he'd never tried anything close to this before, and 'ocean of sound' was an incredibly vague way of describing what even the Faceless Ones had trouble crossing. Would Gabe launch into it as soon as he had the name, or -

"Wait." Skulduggery stopped and held out a hand, but there was no mistaking the way the air rolled against his fingers. "Damn. There's a group of their pets coming up fast." He glanced back at the cave entrance, but there was no way to tell from here if the sigils were still holding - and probably no way for Skulduggery to tell even if he had a clear view. "We may have less time than we thought."
