How it all started

Let's begin….

"It's boring," sighed Luffy one day while sitting in a pub with his friends.
"Yes, you are right," Zorro agreed. "I really want to go on an adventure again," he continued.
Remain silent.
"Got it!" Nami suddenly shouted around.
They all looked puzzled. "Let's go out to sea and go to this weird place that everyone says is not right there !!"
The other diners looked at her with a fearful expression.
But Luffy and Co. agreed.
"Well then .. Off to Silent See !!", Nami shouted, pleased that someone had finally agreed.
So our friends quickly paid with what little money they still had and set off.
When they had set the sails and were already far out to sea and the small harbor could only be seen as a small point on the water, Usopp suddenly screamed around: "Ahhhh ... .. !!!Nami, Sanji, Zorro, Luffy come here quickly !! Dddaaaa …… daaaaa .. a Ggggeist floats !!! "
Loud laughter could be heard. "Man Usopp," ef Sanji from the cabin,
"What kind of garbage do you say again. Ghosts on the sea? Son nonsense!" Everyone began to laugh out loud again.
But Usopp wasn't lying this time, he was sure of that. Frightened, he ran around the ship. Why didn't anyone believe him?
Or was his imagination playing tricks on him again?
No!!! That wasn't my imagination !! That was real !!
The figure moved slowly towards him, he could see that.
He screamed again, but the fog that had enveloped the ship as if out of nowhere seemed to have swallowed his scream.
The fog, which had become so thick in the meantime that one could no longer see one's hand in front of one's eyes, had also made the others restless. What kind of strange fog was that?
But our friends hardly had time to think about it, because a loud, deep murmur made them fearful."Where are we now, Nami?" Asked Luffy and Zorro. "We should actually be at the exact spot called Silent See! Don't tell me you're scared! You wanted an adventure". "But ..." everyone shouted like crazy: You didn't tell us that there is a vortex here that will tear us all down !!! "
Nami was silent. She herself had not suspected the dangers this sea harbored, but now it was too late. "Luffy !!!!!" yelled Usopp, who had meanwhile found his way to the others. "Use your gum gum slingshot !!! Schnelll !! Or we'll all go on it here !!
"Yeah, ok!" Luffy yelled, trying.
The vortex got bigger and bigger. In addition, there was the heavy rain that had started abruptly and a gusty wind. Luffy's slingshot was of no use either. Everyone clung to the ship in desperation. "And now what!" Shouted Zorro, who seemed rather relaxed despite the delicate situation they were in."Wait!", Sanji answered him. He shouldn't have said that, because at that moment the sky was lit so much by a tremendous flash of lightning that they were blinded and could no longer see anything.
They saw and heard something. The wind tore them one by one overboard …….

Will our friends survive this storm or is this the end?
And what happens after that?
