A man was gazing up at the darkened sky.

At first glance, it looked like the night sky, but it was actually just past noon, broad daylight. That alone was enough to tell him that the sky was anything but normal.

As he stared blankly at that sky, a heavy thudding sound echoed in his ears.

Boom! Boom!

The sound, seemingly from somewhere nearby, reverberated around him. Just as he started to wonder what it was, he felt it—a presence approaching from the distance.

Sensing the weight of the presence, he turned his gaze in the direction of the sound.
