Pheromone/Legends

Pheromones were chemicals secreted by lifeform to influence the behavior of other lifeforms, most often to attract members of the opposite sex. Though they normally targeted members of the same species, some species such as the Falleen and Zeltrons had unusually powerful pheremones that could affect other sapient races; these two species were also unusual in that they could exude pheremones at will, rather than unconsciously.
