Tristan's father was Eve, one of the Agustrian knights assigned to protect Lachesis. Both he and Jeanne were eventually taken in by Sigurd's army. However, the two of them were separated some time later. Tristan was raised in Isaach along with Seliph and the younger initial members of the Liberation Army, while Jeanne was adopted by a traveling merchant, who took her to Leonster. After Jeanne's adoptive father was murdered by the Grannvale Empire, she was raised in hiding by Finn alongside Leif. Tristan and Jeanne are finally reunited in Chapter 7 and they vow never to be separated again.
