Augusztus the Battyrus

It dragged you out of the woods, you realized when you gained consciousness. Above you, flapped a Battyrus! So that was the mysterious shadow!
You look around you. The environment is a lake with a waterfall surrounded by trees. It looked like the heart of the forest to you.
Tired and weary, you decided to sleep under one of the trees. Your dream arrives.
In your dream, you hear a voice in your head. The same voice you heard earlier, except it was calling your name. Then, you wake up.
