He has brown eyes and hair. Big stars are clearly visible in the eyes.

After that, he left the burned-down house...

Ato moved into another hut that was. it was abandoned a long time ago.

He put the house in order and began to live there.

One day, he went to get useful herbs for tea, he had an almost empty bag for this.
