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.
Swords form a bond to their wielder. A symbol on the grip that is absorbed through the user's hand and appears on the back of the hand. Maybe only visible to them or others that have the abilities. Could give unique powers depending on when it happened and what they did to get it. It takes a specially made sword that only few can receive and made by a certain race. Then they must do something really heroic to unleash the swords power. Once unleashed it is theirs till they die then the sword goes dormant again till another accomplishes another feat.
