S1·E10 Island of Ambition

With all the Hideauze in the area killed, Pinion and his crew manage to salvage ancient technology not seen anywhere, but instead of sharing it with the rest of mankind as originally planned, Pinion claims that they have the right to keep it to themselves, and sends a message to the other fleets warning them to keep out of their territory. As the message reaches the Gargantia, the fleet had just reorganized itself and there is the concern that other ships may leave to join Pinion's side as well. With the technology salvaged by them, Pinion's fleet defeats a hostile pirate crew who in return asks for a place among them, and he agrees. Ledo, still in shock upon learning the truth about the Hideauze hears from Chamber that the lightbugs that mankind use as power source were also created by the Hideauze as well which further proves their discovery.
