The title of this article is conjectural!
Although this article is based on canonical information, the actual name of this subject is pure conjecture.
Mister Lvellie is the father of Malcolm C. Lvellie and was presumably the family head before his son.
He is quite similar to his son in appearance. He is very tall and has the same strand of hair as his son. His hair, beard, and moustache are very dark. He wears a monocle on his right eye.
His authoritarianism and ruthlessness are part of what made his son what he is now. He is only shown in one panel in which he reacted violently to his son's commentary to Hevlaska.
As a member of the Lvellie family, he was highly placed in the Black Order Hierarchy. He was married following the family's traditions and fatherd several children. He used several of them in the experiments conducted by the Black Order for the holy war. His only offspring still alive is Malcolm.
At some point when Malcolm was a child, he called Hevlaska a killer of her own family. His father, wrathful over such disrespect, violently slapped him.
