Captain
The captain of a ship at sea is in absolute command of that vessel even if higher-ranking persons are aboard. If higher-ranking persons give orders to the nautical captain, such persons are very careful to say what they want done rather than specifying how the orders are to be carried out, because even higher rank does not give them the right to interfere in how a captain runs the ship.
The head of the Captains is the Commodore who shares an equal vote with the other Captains and himself has his own ship. He merely runs meetings with the captain's council and is our diplomat to outside groups.
In the Fleet, not all Captains are simply named "Captain":
Onshore, a Harbourmaster, the equivalent "chief" of a port, was sometimes titled "Captain" if he had merchant marine or naval rank and professional service in command at sea.
The Madam is Captain of The House. She manages a luxurious house of pleasure on the Island where many talented and beautiful ladies reside.
A Guildmaster is in charge of the Guilds, which house the artisans, thieves, assassins, clergy and medics. Rogues are not required to be a member of a Guild, but they cannot be without a Ship if they join a Guild. Rogues in the Guildhouse do not get a vote on the Council under the Guildmaster (though the Guildmaster does take all feedback under consideration when making a vote.)
Historically in the Rogues, The Harbour and the House were not considered Ships, but Guilds instead. Recently, however, the Council has lifted these titles off of the entities and granted them both full recognition as a Ship of the Fleet (despite being located on land).
The officer who is ranked immediately below the Captain of a ship is designated the Chief Mate, or First Mate. The Captain is noted by their name being placed above their ship's flag on their Sashes
There are 2 types of Captains: A Captain of the Colorado Rogues and the Visiting Captain.
