The sudden changes in the movement of the beast race had reached the people of the Hive Star especially those planets near the Beast Star were greatly affected by the invasion of the Beast people. Those who survived the attacks said that the Beastmen had gone crazy. They weren't invading them for the resources of their planet. Those beasts merely want to fight, want to kill, and start wars for no reason. Some surrendered and pleaded to be spared, but the beast race, as if they've gone insane, went on killing, wanting to exterminate those who were on the planet they invaded.
Because of this event, the visitors of the Hive Star had all gone home to prepare. They spoke to the Zerg King Cid Warlock and signed an alliance with them. So, when the Beast Race came closer to their planets, they would protect each other and fight together. Zerg King Cid Warlock agreed to these terms, as it was already expected that this war against the Beast Race would be his responsibility.
