"He's still here!"
Sure enough. the form of Zacharias appeared, on top of his zombie dragon. The beast immediately responded to his master's will, its wounds glossing over as though they'd never been there, flesh re-knitting itself and bone cracking back into place. Zacharias cried out a harsh call:
Where is it, Drake?" Zacharias couldn't sense the Book's presence. Drake was infinitely grateful for it.
"Do you really think I'd still have it? It has been sent away by my magic, to a safe place that not even I yet know the location of!" cried Drake. It was a calculated bluff, as Zacharias would likely expect cowardly behaviour from somebody "below" him. And it worked.
The why did you flee me? cried Zacharias, still unsure.
Drake laughed a dry, coarse laugh, "Do you really think I would sit around and let your dragon rip me to shreds?" Zacharias had taken the bait. He fully believed the Book was gone. Letting out a harsh shriek, Zacharias spurred his dragon into the skies, and flew from the battlefield, screaming curses. He knew there was no point remaining in a protracted battle, so he left to join Nagash, his master. At least that's what Drake thought.
Only when he was sure Zacharias was away, Drake sagged; he was tired. Staggering over to the assembled vampires, Drake awaited the inevitable questioning.
