Dragons unfortunately are uneven in gender with far more males than females. Thankfully elves exist in the world and with some time and effort can be impregnated. During the breeding season of the dragons, it's very hard to concentrate on anything but a mate. So females are given to ride the dragons during this time so they can still scout and go about their day. In return for this, dragons will guard the elves' communities against larger threats and come next spring, the females will give birth to either a female elf or a male dragon.

These times can be trying and very intense for the females but are considered an important rite of passage that each one should undergo to appreciate their dragon protectors. Of course, after going so long with a dragon mate and the rarity of females, it's not unusual for dragons to end up with an elf wife, raising a happy family.
