Once upon a time, in a kingdom 20 miles away from Gravity Falls, an old king started packing his items up in his suitcase. He was Dipper and Mabel's grandfather, but he didn't know that for Dipper and Mabel Pines had not been born yet into this world.
Well, the old king was banished from the kingdom after doing a crime so horrible that the people demanded that he be banished. Like his nephew from his sister's side, Stanley Pines, he was kind of a wicked person, but Stanley had been vanished many years ago and only god knew where Stanley was now. He knew that he would soon have to leave the town or the police would come get him, so he called for his most faithful and trusted other nephew from his sister's side- Stanford Pines.
Stanford Pines soon entered the room, existing for his science lab where he studied and learned most of the day and when the old king say him, he smiled. "Ah, Stanford! My most trusted nephew!" and he drew him near. The old king's voice was sad as he said, "I must leave the kingdom soon my dear nephew. I have done a crime that made my people want me to leave, but before I leave, you must promise me something. First, promise me that you will be as faithful to my son as you have been to me."
"Of course, uncle," Stanford said.
"Next, promise me you will show him the entire castle, except for one room. Do not show him the room with the picture of the red hair princess. I fear it will cost him his life."
Again, Stanford promised. Without hesitation.
Then the king took his suitcase and forever left his kingdom.
Then the new king was crowned and Stanford showed him around every single room in the castle. Every single room that is... except one.
"What is that Stanford?" asked the king, pointing to the room.
"Nothing, younger uncle, now let's move on."
"Aw, come on! Can't I see?"
"No, you don't want to go in there!" Stanford said firmly. "Your father said it could cost you your life!"
"Really? Nonsense!"
He pushed the door open with such force and soon came face to face with a beautiful portrait with the most lovely girl he ever did saw. He fainted.
A while later, he told Stanford that he wanted to marry this woman, but Stan refused. "You'll get yourself killed! She's cursed! If you marry her, you and the children she'll have in the future will be cursed too! Don't do this!"
The king turned to him and said, "I think you want to steal the girl away from me Stanford. That's why you won't let me ask her to marry me. You want her for yourself! Mmmmf! Some faithful nephew you are."
"No, younger uncle! That's not-"
But he didn't finish his words, for the King, thinking he was trying to steal his girl, took out his gun, shot him and Stanford Pines, lay on the ground, dead, blood pooling out of him.
The King, soon felt very sorry for what he done. "Oh, no! What did I do?" He fell over Stan's body and wept. "I can't believe I killed my own nephew over this woman!" he wept. Yes. He had killed his faithful nephew over a stupid girl. And in an effort to remember Stanford Pines, he painted him in gray and putted him on the floor as a statue in front of the door. Then he set off to find the girl of his dreams with a bit of unhappiness in him.
