I have a secondary character that is overly bubbly, and possibly a bit too nice. However, what I am most curious about given her species (still sorting that bit out for the story), the females emit a potent pheromone that has a calming effect that can affect an extremely broad range of other alien species. This would be part of her species evolutionary development, due to the males of the species being highly aggressive and dangerous. Think of a new human mother that produces a similar pheromone that is less potent, called HAP (Human Appeasement Pheromone) that is produced in the areolar region of the breast. (Yes I did check to see that this is a real thing.) Which increases after a child is born. Back to my character, which can produce a similar pheromone pretty much whenever she chooses to, which can increase substantially in high stress situations or during arousal. Which makes her kind better suited for jobs that deal with others that have anxiety, such as in various medical fields or tattoo/body modification parlors. (The effect can take anywhere from approx. 5-10 minutes given the other species aggression potential and amygdala size in relation.) Alright, given the information about the character's physiological capability to calm down even the most anxious or angry aliens they may cross paths with, is this too weird a concept? What other thoughts do you have about the concept? Thanks.
