When the Alliance sent aid to the Night Elves after the burning of Teldrassil, a legion of breeders isn't quite what Tyrande had initially had in mind. Over time, she came around to the idea, and it's fairly common to see a few elven women being bred at any settlement they occupy, or more accurately, to hear the moans and the plapping of flesh long before you see an elf bouncing on the cock of her white human breeder. Try as she may, even Tyrande herself was drawn into all of this, on her knees before groups of breeders, blowing them to get them ready to fill the wombs of her sisters.
