Luche and Bart once experienced a loving relationship that was generally smiled upon by both races. This intimacy resulted in the birth of Arche. However, the elven race soon developed a great animosity toward humans and choose to isolate themselves in Ymir Forest and form an Elf Colony. Not all elves agreed with this isolation, but it eventually became mandatory. The elves forcefully ended Luche and Bart's union by taking Luche away. Luche requested that Bart hide the truth of their separation, so Bart led Arche to believe that her mother had passed away.
