With the Body free of the creatures grasp Sage was free to act. and what he did would most likely get him in alot of trouble for a few reasons but... oh well. firstly he threw off the robe. (strike one) Secondly he invoked a demon, granted it was a demon that he had known since childhood and wasnt evil but it was still a demon. bonding his spirit to its his skin darkened a few shades, and his hair became wilder. with one Air powered jump he launched himself into the air, higher than the creature as it was preoccupied with erik and Ven. the commonly held belief about any avian monster is that they dont look up, and they reall don't. so when Sage slammed down on the creatures neck from above and took a physically enhanced deathgrip to its neck the beast was caught off guard and went buck wild. so Sage just held on for the ride. Like an aerial rodeo.... with two hands
