The precursor of the Mother of Demons, Moya, Mnemosyne and Laine have harbored a grudge for quite a long time, although this so-called grudge has always been unilaterally perceived by the other party, and Laine has never paid it any attention.
It was not until this Goddess of Titans suffered a loss at the hands of the newly born Atlas that her existence truly caught Laine's attention as she chose to dive headfirst into Tartarus. Now that she has lost her former appearance and turned into a form even more twisted than the Hekatonkheires, one can only imagine the resentment that smoldered within Moya when she awoke.
She had gained the power she had longed for, yet she had also turned into a monster unrecognized by the deities. Had it not been for Tartarus, which had birthed her, guiding her choices, and had she not set her sights on Hell to draw from the power of the Abyss after her descent, Laine would have been well-prepared to encounter her in the Spirit Realm by now.
