Michael's eyes narrowed as he observed the threat carefully. When it came to the little aliens that flew around the area, they were mostly harmless, unless provoked. What categorized the danger of the Ro'trah's herds was the queen leading them.
Higher tier usually meant that a bigger swarm was under the queen's control. Not only that, but the stronger they were, the more effects they would have on the herd.
For instance, they could make them fiercer, faster, or increase their reproducing speed. These queens were naturally tremendous threats that needed to be eliminated. However, with the herd protecting its mistress, it was hard to reach them.
Of course, while the little creatures were now following the queen's command, the queens themselves would always obey their one and only ruler. Thankfully that ruler was light-years away, bringing peace to Michael's mind.
