Typically, the voice of reason in myths is represented by a wise elder or a sage-like figure, such as Merlin in Arthurian legend. These characters often provide guidance, wisdom, and moral compasses to heroes facing profound challenges. They represent the collective wisdom of a culture and often help mitigate conflicts or navigate complex situations. Through their insights and counsel, these figures exemplify the importance of knowledge and experience in making difficult decisions and shaping the course of events in mythological narratives.
