"Wait a moment." Lancelot used telepathy to communicate with everyone, "There's something below."
Though they couldn't respond verbally, the leader, Danks, immediately reacted—he lowered his left wing, raised his right wing, and tilted his tail feathers upward, causing their direction to shift left while allowing them to conveniently observe the situation below. A few companions, who were not very adept at flying, squawked loudly but eventually followed suit, spiraling in place with a radius of about thirty feet.
"Everyone, pay attention to the north, under that lightning-struck crooked tree," Lancelot's voice sounded again, "You may not be able to see it clearly yet, but there is an undead squad there, escorting a few suspicious wagons. We'll follow them, and if an opportunity arises... you know what to do."
