The mask [on hold]

When you think that everything is going to be alright, everything goes wrong.
Our land is in chaos, our princess disappeared, our King collapsed after his daughter went missing.
And between all those chaos, he appeared.
No one knows who he is, or what he wants. He’s wearing a mask as black as the night, he’s dressed in a black cloak, riding on a horse. A horse that is so black as the ash from a fire.
He appears, fights, and disappears again.
After a few months, the prince of the North came, the princess was promised to him, and he wanted her. Our king had to face the fact that his daughter was gone.
The kind regained his strength to rule over the land, but he rules with a cold heart.
They say that the prince from the North is searching for our princess, to make her his. But at every step forwards, the one with the mask appears, and force them to stop. One step forward, two steps back.
Our king has placed a price on the head of the one who wears the mask, but no one knows, who the mask is, and why he does what he does.
Who is the one behind the mask, the mask of the night, the mask of secrets, tears, blood and death?
