Fallen kingdom (itch) (peterson2019)

Once upon a time

There was a kingdom
A cheerful, rich and peaceful kingdom
But
A mage came by
A mysterious and wise old mage
The mage made a bet against the king
And the king
Confidente of himself
Accepted the bet
And that decision led to the fall of the kinsom
And took over the city
Making death fall upon countless lifes
The king
Desperate for help
Send his fastest messenger
Calling for the help of his son 
The king's son came by his fastest horse
And decided by all means
He would repair the kingdom and the mistakes made by his father.
