Daughter of the Blood King/Trick and Isabeau. Aife is a succubus who refused to choose a side (Dark Fae or Light Fae). Aife is insane from her time in the Dark Fae dungeons where the Dark Fae imprisoned her after Blood King/Trick turned her over for justice for killing a Dark Fae leader. Aife was kidnapped (or rescued from the dark dungeons, depending on who is telling the story), by Hades, god of the Underworld/Tartarus, who impregnated her. Bo is their child.
