Faced with this task, Charles's first reaction was, "Why not kill them all?"
But he immediately knew this was somewhat impossible.
It has been inauspicious to kill prisoners since ancient times!
Especially since both Menilman and his Westwind Knights had surrendered too many pirates, killing so many people in one breath would disperse the loyalty of those who had already surrendered.
Absorbing them all was definitely not an option either!
The lower-middle class pirates might still retain a shred of humanity, but among this group of pirates were either loyal guards of Golden Ram Herolf or crew of the Magical Alchemy Warship. There were too few good people and too many bad ones, nearly all of them heinously evil, including a number of Transcendents. If they joined the fleet, they would certainly hold relatively high positions, affecting Menilman's decisions.
Charles hesitated for less than a minute before making a simple decision: transform them all into Labyrinth Guardians.
