Alfhejm is a world where there are only female Elf. World source of Mana "Shrine" has run dry and the Elves could remain on the brink of extinction. But then they remembered the prophecy which stated that from another world will come "man" and save the elven race. Waiting for "hero" was not as long and he appeared out of nowhere. The essence of salvation was the institution of children from "hero". Many of the Elf were unable to come to terms with this "Salvation of race" and separated from the group. Actually all Elf shared into two warring camps. Soon some of the followers of pregnancy from the man began to realize that sex and sperm will improve and enhance magical ability, and the more often they get a portion, the stronger and powerful than becomes their magic. For "hero" began to have bad times.
