The Black Wind Pirates Group was utterly taken aback by the Insect-men's ability to fight in space. Was this the power of a level three civilization which was barely scraping by? This was nothing like what they had been told in the reports!
Romero also discovered that this was truly a pirate group encompassing a jumble of species, including many slaves who had been forced to join the group. Meanwhile, the Insect-men warriors didn't hesitate to attack anyone, their strategy simple: to annihilate the enemy. In a place like this, being merciful to your enemy equates to cruelty towards oneself.
Regardless, this was good news - they couldn't destroy the ring-shaped spaceship, they needed it to tow the merchant ship back.
