Rahna

Rahna is Levn's mother and the Queen of Silesia. In chapter 4 of Seisen no Keifu, her brothers-in-law, Daccar and Maios, rebel against her due to each of them wanting the throne for themselves instead of Levn after her husband, the king, passes away. During the time Siglud is in Silesia, Rahna supposably acts like a mother figure to him, but due to Levn running away, she purposely ignores him. After the death of Mahnya, the capture of Silesia Castle, and the liberation by Siglud, Levn goes to Silesia Castle, has an emotional and inciteful conversation with her, and she gives him the Holsety tome.

It isn't known whether Levn's father, the late King of Silesia, or his mother, Rahna, is the parent that Levn got his major Holsety holy blood. Neither Daccar or Maios have any holy blood, and due to the fact Rahna doesn't refer to them as brothers, most people have come to believe that Daccar and Maios are her brothers-in-law, thus most people belive the late King of Silesia must not have had major Holsety holy blood if his brothers didn't have it, so Rahna must have major Holsety holy blood. Whoever, if Daccar and Maios were only half-siblings to the late King of Silesia (Daccar and Maios are referred to as Levn's uncles, so this is unlikely but possible since the game calls Yuria Celice's sister even though she is his half-sister), then he could have major Holsety holy blood.
