Unheard Bell Flashback Arc
At some point, when Lyza formed a team consisting of multiple black whistles assigned beneath her, she met Torka and, much to her peers shock, fell in love and became wedded to him. Some time after, Lyza would become pregnant, but with the worst possible timing; right when their expedition Greater Artifact, the "Unheard Bell", was discovered hidden within the 4th layer of the Abyss. The discovery sparked a fierce competition between delvers from enemy countries and those of Orth to retrieve the extremely valuable relic, and Lyza was tasked with leading a squad of black whistles along with Ozen.

The expedition took 11 months, most of it including Lyza's pregnancy, and her husband Torka perished during an unknown incident with other delvers.
