The reference
After reading a book called "A verdadeira Ilha do Tesouro" (The real Treasure Island, in free translation) by a Brazilian author named Marcos Juliano Ofenbock, I came up with an idea that could add some adventure to the Sea of Thieves universe. This book tells the story that could have given rise to Robert Louis Stevenson's Treasure Island.
Starting the Tall Tale
The event would happen randomly, with some restrictions before it start. The player would have to be logged in on the server for at least 1 hour, and would need to have completed any mission. The reason for this is to prevent players from getting in and out the server in order to get this Tall Tale. The idea is that it's as rare as the White Meg event or the Box of Wonderous Secrets, because the rewards are so high.
In the tavern, while a player is inside, a NPC enters the tavern with the broken leg animation and white name (like an enemy player). He stops at the tavern entrance and beckon to you (same gesture as the players). He is an NPC that can be killed and the chance to start Tall Tale is lost. To receive his book, you must face him and beckon too. Done, Tall Tale is started and the book is received.
And the treasure hunt begins
He introduces himself as Ofenbock, Zulmiro's last survivor, a galleon that was sunk by skeletons. He says the galleon carried the largest treasure ever seen in the Sea of Thieves, which could leave any crew millionaire.
Knowing they would be hunted, Zulmiro's crew stopped on an uninhabited island and hid all the treasure in a cave. Skeleton ships appeared as soon as they set sail from the island, Zulmiro sank, but he managed to survive by fleeing in a rowboat carrying the book showing the location of the treasure.
He says your crew's reputation has reached his ears, so he has decided to entrust you with this task. On the way to meet you and your crew, he hid the remaining pages of the book in a chest, threw the key and into the ocean and hid the chest in another island. Of course, everything is noted in the book.
With the book, we have a history of how the ship was sunk and an indication of where to find the key. The key has been thrown overboard, but it's near some island.
To get the chest, we use the same method as other Tall Tales, the book indicates where the chest is, you need to go there and open it with the key. When you open the chest, you receive the remaining pages that indicate where the treasure is.
On the treasure island, another NPC saying that recently there was a landslide, and hinting that it would have to explode the passage to enter the cave. The idea here is to gather several powder kegs, maybe 10, and blow up the entrance.
Inside the cave, we will actually have the greatest treasure that could exist in Sea of Thieves. I believe that really 1 million gold would be interesting, because being a rare event would not affect the economy of the game. It would also be interesting an amount of doubloons and ancient coins. And of course, a title for completing this Tall Tale.
And not over yet
Of course it wouldn't be so easy to find the treasure and sell it. The idea is that the moment the ship leaves the island, some Skelly Ships appear to disturb. Besides that in the middle of the treasure we will have some reaper`s chest.
TL;DR.
A random Tall Tale happens after completing some specific tasks. The chance to receive this Tall Tale is equivalent to finding the White Meg. This Tall Tale guides you to a treasure worth 1 million gold and other prizes.
