Fen also added some hot knowledge. The sea lanes on the map were just general directions to anchor a rough path without getting lost. The specifics of the path were determined by the wind, not by men.
Having power to take a relatively longer route was faster than taking the shortest route without power.
There were so many pirates on shifts on the ship to adjust the sails and rigging for a better angle to face the wind.
That was why there was such a thing as a navigation log, to record various minute adjustments, the speed in knots, the direction taken, and the effects of the weather and the sea, so that one could know their position on the map.
Fen, who understood astrology and astronomy, could be called a dodecagon warrior. He could determine his current position through phenomena such as the angular distance between celestial bodies, azimuth angles, and so forth, but he still needed double assurance.
