A day quickly passed, and the four major Sky Cities, including Rocky's own Thunderhawk City, entered the airspace controlled by the Mairente Family!
Their arrival was without any notice, which seemed unusual—normally, there would have been, because there were rules in the skies: abruptly entering the airspace of others equated to declaring war, and the owner of the airspace could attack directly.
Even if Rocky did not know this rule, the city lords of the three large Sky Cities and the military commander Claudy certainly did, yet none of them reminded Rocky.
Because there was no need.
For any member of the Rebel Army, the Alliance had no intentions of following the rules. Moreover, Claudy, who was in charge of commanding the troops, would probably hope that the opponents would attack first, giving the Alliance a reason to annihilate the family!
