Angel keen: Vita tree 

In the heart of Berthai where it was once the beautiful forest ever existed, Keen landed on the ground right in the middle of dried wood. It was her real home which had been destroyed long ago. People call this area the end of the world where you face dark. No one had that much of manhood to stop there. Her wings changed to cloak and she walked among the Dead forest. Branched made horrifying shadows on the earth. The air was gloomy and she dismayed that sense which has been spreading around her. She strode forward to the famous Vita tree that king Merithia mentioned. He was talking about a dark cloud streaming out from it. So she guessed it must be the same invisible cloud she discovered around Persis castle.

"You arrived on time Keen, can I accompany you?" Dra came out behind a tree. 

She eagerly smiled, this commander had an amazing aura that she loved. She felt safe anytime he appeared around, "I'm always on time! Let's see what made this Vita tree dark".
