Thirty naval officers to sail the seven seas, salty sea dogs all. Some are explorers, some are traders, and others are out on missons of conquest.
Seven naval commanders with the power of life and death over their men when at sea. Theirs is a lonely post, as they are responsible for their men and the ship that they sail in. Some are legally appointed, others are mutineers with not much to lose.
The Admiral of the Fleet, an exemplary commander, peerless in skill, ruthless in execution.
Also happens to be a 14 year old girl.
You find a patch of edible funghi. They taste well and all, no ill effects. UNLESS you consume some beverage, even 3 (three) days after eating it. Then you become really sick with pains, vomiting, all the fancy stuff. As a gift or good meal, it could be a cruel joke or to make sure the heroes spend their time focused on the mission. And the fine soup you had in the inn yesterday could have some in.
(Inspired through a real-world fungus. Was really used to cure alcoholism.)
