Whatever was going on there, was pretty strong. And even though his instincts screamed for him to mind his business, his curiosity took the better of him and he jumped down from the roof, his wings spreading out to slow his descent.
The wind filtered through his wings, the sensation of the light feel bringing in him an excited chill. Here he was, putting the wings to more practical uses rather than just gliding over mountain tops and then choosing to walk when they had to come down to plain walk instead of just gliding down to level ground.
He shifted his body, twisting to the left by leaning in that direction to avoid colliding with humans. At the very moment, he was in the space between invisible and visible, meaning that there was a 50/50 chance that his body could be physical to some people and as a result, he could just as well bump into them.
