"I guess I need to consult father," Rain thought.
Rain's desire to create these waves of power stemmed from his desire to build a force that the Raging Phoenix could rely on consistently, regardless of the adversary they faced. While magic users and allies could certainly be valuable in specific situations, Rain wanted his core group to be self-sufficient and able to confront any threat that came their way.
This self-reliance was particularly important because, as strong as they were, the Raging Phoenix needed to be prepared to face not only dragons and beast people but also the potential challenges posed by their former allies or any other unforeseen enemies. Rain understood that their ultimate goal of protecting their territory would require an unwavering strength that could withstand all adversities, and these waves of empowerment were his way of ensuring just that.
