They step back and continue to watch vigilantly. Soon, a barking howl is heard at the forest's edge. The pack raises their heads and ears to listen as it repeats three times in a different variety of ways, and then respond en masse in barking howls. They then run down the mountain toward the forest.
Gus quietly watches them and the display, furrowing his brows as he watches as they howl and bark and then continue down and along into the forest where the first signal came from. "Organized pack animals... Damn." he says, looking down and at his own encampment and squinting over his meager possessions and defense.
"If they come for me during the night, I guess that'll be it." he says, furrowing his brows over before he looks up to squint at the sky, checking the time of day. Once he's made himself sure of something, he beings to slowly and surely shift around his camp, digging out small holes to fit pieces of wood into to make torches, small firepits, whatever he can manage to surround his camp with. A beacon more than a simple campfire is, but fire usually keeps beasts at bay.
Once he has finished that, it's simply a matter of sitting back and relaxing- continuing to wait and heal up a bit for he can get on his feet again.
