Koschei the Deathless

This is a story based on a Russian fairytale. I hope you like it!

There was once a closet in which no one in the kingdom was allowed to enter. No one knew why, but the king ordered it, so no one did.
One day, the king's son, Prince Ivan, had discovered the closet. It was shut because a wooden hand locked it.
Prince Ivan went to touch the hand. And the moment he touched the hand, it slapped him. Prince Ivan saw blood coming out of the hand. When opened, Ivan saw a doll in red paint.
"Ha! A silly doll. I wonder why my father banned the closet from being opened."
But he didn't notice the doll had transformed into a strange man with a hunchback and long arms. "Thanks, friend."
Prince Ivan turned around and screamed.

"Father...I just saw a-a-a doll transform into a-a-a person." "Let me guess. You opened the closet," said the king. "Yes," Ivan admitted.
"Well, there is nothing we can do about it," said the king. And to this day, we know this man to be Koschei the Deathless.(He is immortal) Some claim that he roams the land to this day.
As for the closet-it vanished.
