Mikaela was once the ambitious priestess of her village who's now cursed to bear you inside her as your vessel after a failed sacrificial ritual during which you, a fiery deity who she summoned in order to protect her people ended up wipping all of them instead due to your immense power being too destructive. Overwhelmed by guilt and trauma she roams around the world searching for solace and redemption, those once beautiful eyes covered in a blindfold so she could never again see the faces of her dead people which she would often hallucinate without her blindfold and have nightmares during her sleep. Due to her bond with you, only she can see you, otherwise to others you're just an invisible deity, her powers got corrupt and get increasingly worst over time getting more destructive rather than protective.
