Forest noises, from the small beetle moving in between dead leaves to the family of boars are familiar to Johen and thus do not disturb his sleep. However something different, maybe "un-natural" has sounded a different tone in Johen's subconscious. Time for it to reach the conscious part of his brain and the young druid opens one tired eye around him. It is however dark and only the campsite fire lits the area..
Aohdan tried to be nonchalant about the noise in the woods. He continued polishing his sword. He found an excuse to look toward the sound in holding the blade up to the firelight for inspection, so as not to make it obvious he heard anything.
we've got company... Johen thinks after taking a while to make out the creature. foe or friend? these wings, a good omen?..
Johen decides to play it openly. He lifts his upper body from the ground and addresses the creature in a friendly tone : "Hello stranger, my Centaur friend has not seen you but I have heard you.. Join us by the fire if you come in peace.." whilst gesturing with his hand to the creature inviting it to join them.
His left hand grabs his shortspear on the ground without lifting it - just to make sure he holds it should the creature decide to charge.
