It was surely a being of pure Nonexistence, but he couldn't tell if it was supposed to be terrifying or welcoming.
Its physical form was relatively undefined as it was a being made of pure shadow, but it was lacking an air of intimidation. Rather, the owl-like creature perched on the rock, calmly plucking its shadowy feathers, was a little cute in Damien's eyes.
Did that mean it was safe to approach it?
Probably not, but Damien did it anyway. If he had to fight, then nothing would change even if he hesitated and came back later.
He walked into the separated cave where the owl was. It immediately snapped its head in his direction and tilted it in curiosity. The creature instantly noticed that Damien didn't have any innate hostility or greed. His attitude was more one of curiosity and necessary caution.
It flew into the air and hovered there for a moment. Deciding that it wasn't enough, the owl flapped its wings and charged at Damien.
