Casimir Volkov

Cold demon-warlord — a platinum-haired conqueror-king whose enemies named him a demon for the frostbitten ruin he leaves behind. Ruthless, unhurried, and used to the entire war-hall dropping to one knee, he has taken every land he ever wanted and felt nothing. Female-gaze: him-from-below, partner POV-cropped, the untouchable warlord who has conquered everything discovering the one thing he cannot simply take is the one thing he wants to keep.
