Winged Cats

Prologue

The Stars are shining brightly in the night sky, illuminating the forest with its glow.
The only sound in there is a slow wind humming quietly between the trees and grasses and the little sound of a flowing river, but there's also something that can easily ruin the peace of this place.

Something mysterious is walking through the halls of the long, long cave. It goes slowly down the dark, rocky path before standing at the edge of the cave on the big rock and looking at the sky with unredable expression.
It's hard to see what the creature exactly is, in this darkness.
It looks similar to a wolf but its eyes are pure white without pupils, its fur is unnaturally black, shining slightly in the night's air, and the tip of its tail is looking like a mist, that's dragging on behind it, for a while before turning into nothing like if this never existed.
The creature looks up at the moon, that's white colour turned into red for this one special day. The misty wolf slowly closes its eyes and breathes the cold air for a while, before slowly pulling its head down to the chest and opens eyes, watching the trees in front of them.
They seems like hesitating for a few moments before slowly reaching their paw to touch the grass.
Every one grass under the black paw, violently reacts to the touch, it starts to wither leaving only a dry mark in the form of a wolf's paw, on the ground.
After a moment The misty wolf shakes its head and walks slowly to the woods, leaving dried paw's marks on the grasses.
Their tail dragging slowly like a mist behind the creature.
After a moment of walking it stops next to a tree and digs its claws into the bark before lifting themselves onto a branch.
The creature sits carefully on the tree branch when it trembles violently under its weight and cracks slightly.
The misty wolf sits still for a moment before digging its one claw into the bark in front of itself and drawing five lines before pulling its paw away from the mark, to look at it.
The mark is looking like an eye, with four lines as the form of the curved diamond, and with the one line on the middle that's supposed to be a cat's pupil.
The creature watches the symbol on the bark, for a few minutes and after that it glances at the red moon's shine before standing on the shaky tree branch, and jumping down to the ground, landing perfectly on its all fours.
They shake their head slowly after it, before slowly heading back to the cave, that's looking more like a thin mountain, with a big hole near the ground, than a normal cave.
The misty wolf turns back to look at the forest for the last time before it goes to its hidden spot. Its tail dragging limply behind the creature disappearing into the hall of the dark cave, leaving the peaceful woods for the next few months.
