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.
What about a 'criminal' society with distinct laws - for stealing, the larger the value of something stolen, the less punishment the courageous thief recieves (but must return it of course). For this pirates(?) caught petty thieves deserve to be punished harshly. If you take, you better take a lot.
