Here, since I have time on my hands, let me show you what a comprehensible (if not good) fic would sound like. I've gone ahead and made the assumption that the crew escapes from Thriller Bark alive and Brook is with them. This could easily become obsolete in short order (hence the danger of doing such things), but for the purposes of demonstration:
Night. The winds of the Grand Line howled, and a torrential downpour which had not ceased in the three days since the Straw Hat Pirates fled from Thriller Bark pelted the hull of the Thousand Sunny in an unceasing rhythm, counterpointed by the slow rocking of the ship. And for the third day straight, after Robin had relieved her of watch duty at midnight, Nami found that sleep simply would not come. She had tried before to simply shut her eyes and let her weariness carry her where it may, but all the while, her mind raced with the recent events and a growing feeling of unease she simply could not shake.
Ace. The Warlord Kuma had mentioned Luffy's brother. Had asked her directly if he had one, and she, taken by panic, replied in the affirmative. I see, the Warlord had said. What did it mean? She couldn't be sure herself, but she knew that it couldn't be anything good. And if she told Luffy, well… Luffy being who he was, he'd probably jump to conclusions and order the crew into doing something beyond rash. Still, it wasn't right for the third-in-command to be hiding things from her Captain.
And then there was the weather. By her calculations, they should have left the Florian Triangle two days previous. The Log Pose still pointed ahead and slightly down, as it had since they set their course, but the unceasing rains had clouded her thinking, and made her question her own unfailing sense of direction. At the very least, she'd be a lot happier once the storm let up. Heaving a sigh and wrapping herself even more tightly in her blanket to keep out the unrelenting cold, Nami finally gave in to exhaustion and fell into a fitful sleep.
As she watched overhead at the familiar scene replaying itself for the thousandth time since it happened, Ace instructed Luffy to keep a particular slip of paper safe. Luffy was to look at it only if something happened to his brother. They had sewn it into his straw hat, since that was the only thing Luffy ever showed any kind of serious concern for, but… what about it? Maybe given the current circumstances, they should. . .
"Miss Nami!"
The scene dissolved before her as a refined, gentlemanly voice greeted her ears.
"Miss Nami, do wake up! It's urgent!"
Groggily (for her sleep had been listless and not restful in the least), Nami rubbed her eyes, and murmured an answer of "Hold your horses, I'll be right there." Turning towards the voice, she found herself staring into the empty sockets and permanently-etched grin of a human skull.
"KYAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!"
Nami's cry of horror, followed by what could only be the cracking of bones, echoed throughout the Sunny.
"Nami-baby, I'm coming to rescue you!" came a voice from elsewhere in the ship, but by the time Sanji reached the women's quarters, Brook was already on the ground, an inexplicable red bump rising from his bleached skeletal forehead.
"Yohohoho! Yes, it is I, in the flesh! Or at least it would be, if I had any! Yohohohohohoho!!"
The living corpse's laughter only further inflamed Nami's rage, and, grinding his wrist bones underfoot, she demanded, "What do you want, you undead pervert?!"
"Oh dear me, such a temper," said the skeleton, as polite as ever. "I'm sorry to intrude, Miss Nami, but I have urgent news! You must come outside!"
Grumbling about Luffy's latest acquisition under her breath, Nami made her way out onto the main deck. The sight that greeted her took her completely by surprise: a marvelous morning sky, with still a hint of lingering twilight. The storms of the past three days had dissipated, and in their place, a light breeze out of the northwest stirred the warm summery air. But, contrary to the instructions she had left with Robin the night before, the ship wasn't moving.
As if in reply to her unasked question, Robin pointed (with a disembodied hand) to Nami's Log Pose. It was pointing straight down. . . .
See, that's something that might actually capture someone's interest (though I make no claims as to the quality of my own writing).
