Khroma first appears with Alexei in Heliord. She then appears later in the story, at the Weasand of Cados in her dragon form absorbing the concentrated aer, stabilizing it. Later she was seen again in her dragon form transporting Duke Pantarei in Yormgen after the group discovers it is in ruins. Khroma appears at the castle of the aer-ridden Zaphias before fighting Estelle, telling them that Alexei was ahead, and that she wanted him to be stopped. At Relewiese Hollow, it is revealed to the party that Khroma is one of the Entelexeia, although Yuri already suspected this beforehand.
