Galai is the youngest princess of the Crimson Courts house known as the Blood Wings. Her older sister killed Legius' father and the current Crimson Courts king, Deus Artorius. Legius would thank her by making her assassination his engagement date with Hera and crushing the Blood Wings alongside Hera their honeymoon. From there he'd let the Blood Wings live so long as they gave him a fitting peace offering, to which they offered Galai to be one of his sons' wife when they were of age. Legius would accept. This deal would prove useful as despite the Warbringer (the supposed genetically perfected red soul) being born, he wished to see how far he could take perfection and Galai just so happened to be the perfect match to continue the Artorius Project.

Disgusted by this as they more saw each other as found family, the Warbringer fled and Galai would remain under the watchful eye of the Artorius house until the Warbringer returns to claim his throne and her hand. Currently she is guarded by Legius' runt, Azrael. Ironically, they would begin to develop a forbidden love as Azrael was considered too weak to breed and would actively pollute the Artorius bloodline if he did. Not to mention the fact Legius wanted Galai to marry one of Azrael's brothers. The pair would express their love in secret as they slowly look for a way to escape their families.

Galai is caring and affectionate, but stays silent most of the time as to not give anyone any ammunition to use against her later. She's aware of her royal blood and hates it. If she had the word she'd relinquish her royalty and live as a peasant, at least she wouldn't be a pawn in a big game and be thought as nothing more than breeding stock to continue an inane project that she believes is going nowhere and ruined her life. If the Artorius house had but one throat, she'd slit it. Except Azrael, she likes him.
