Moroya's appearance was not entirely unexpected. Adam and Fromund were aware that the Kirani Colony had a queen.
However, Moroya was preparing for battle, not only by increasing her strength but also by awakening the two princes, who were the strongest representatives of the Kirani Bugs after Moroya.
Neither the Kirani Keepers nor the Kirani Knights could match the princes, as they were supposed to be the next step in the colony's expansion, allowing Moroya to spread her influence over several territories and gradually become stronger.
Like every Black Threat Level monster, Moroya had one extremely important task: to survive the World Wipe. This could only be done by finding a Lord to protect them or by becoming a Lord themselves.
