sitting in the forest near a river at night, it was nice, the moon was bright, the stars were out, the only sounds being the chirping of crickets and the gentle rustling of the stream.

you always did this, going out at night to relax, but today was different...there was another sound, like the flapping of wings...? But slow, and somewhat uneven, like a big bird? But that sounded a bit too big to be just a bird. Eventually the flapping would stop and you'd hear a slight thud not too far from you on the grass.

you decide to get up to check what it was, walking along the river, you eventually turn to look between some trees, and you see a skeleton on the ground, but not just a skeleton, he had wings, and he was laying on the ground as though he was injured.
