Sir,
I am writing to you from a plantation in the greatest of secrets. I am currently assigned to the service of the preceptor of the children of the master of these places. This is how I was able to learn their language, as well as yours. I have learned from other brothers, slaves working elsewhere in this colony, that my wife, daughter, brother and nephew are subjected to despicable treatment.
I absolutely have to help them. I would do anything to get them out of there.
One day, I overheard one of the suppliers on our plantation talking to the master's children. He told how a pirate had managed to find treasures, only with his head, his intelligence, without ever fighting. He was talking about you, and how you help people.
Hearing this, I thought to myself that you were one of those pirates who free slaves when they capture slave ships, rather than reselling them to the highest bidder, as if they were cattle ...
You know, I could escape on my own, at great peril, and try to join everyone who fled into the surrounding jungle. But that's out of the question, not without my family.
I thought then that you could help me with a plan that would allow us all to escape. Because you see, we are spread over 3 different plantations, in a fairly large colony organized around a network of rivers. I need someone who could both decipher coded directions to find us, and wield a ship with dexterity to stealthily ascend rivers.
My contacts have passed on instructions to my family, asking them to be ready for the next moon. They will be waiting for you by the river, near their respective plantations.
Please accept.
I have no money. I will take with me some items that I used in the master's house. I'll pay you with it.
Songo.
