The first is as follows: Females mature at thirty years of age, whilst males are fully mature at around forty. It is then that they will leave the group where they have spent all of their childhood to wander alone, searching for a partner to spend their life with. This search can take an infinite amount of time, the average time taken being around four years.
When the female eventually has a partner, the two Unicorns spend a year together, wandering alone before eventually mating. This process itself is spread between three days, the pair couple roughly sixty times throughout this period.
Gestation is long, around two and a half years, but yet the female does not swell with the pregnancy as you would expect, until the very last days.
Birth is quick, and the young can stand within hours. Then, the pair begins to travel once more, and will rarely have other young until their offspring has matured.
