William considered the animal cautiously. It didn't look all that dangerous to him, but then, neither did unicorns, right up until the moment they realized you had testicles. Equidae were a wholly unpredictable taxonomic family in general.
He walked slowly toward it, hands out in front of him as if to pacify the creature, when all he was really accomplishing was giving it a target to bite first. "We need Jon," he lamented, but as he reached the creature's side and crept in toward the pouches, it swung its head away from him, looking bored and uninterested. That could very well be a trap, of course, so William didn't let his guard down. He did, however, find some items of interest as he slid the first pouch's buckle open to examine the contents.
"There are drawings of art," he told Pete, surprised enough to raise his voice unwarily above a whisper. The pack animal's ear twitched in warning, and William immediately dropped to a more appropriate and soothing volume level. "And archaeological tools." William had been fascinated by archaeology as a child; he had watched the infamous Jones documentaries a dozen times over. He appropriated a few of the tools for closer investigation, but they were unfamiliar, clunky and gleaming.
A nudge at his hip startled him into an undignified squeak, and he jumped back a foot to see the mystery creature studying him with ill-concealed boredom. William kept an eye out for teeth and held the packet of pictures carefully out to the side for Pete to take. "Are we perhaps meant to be looking for something?"
