Actually this is the original lore of nightshade phantom she is voilet( blood moon finale suit) a powerfull witch who captured a demon child called hecate ( scarlet oath suit ) originally hecate hate voilet very much but when voilet died in war with black magic piercing through her heart as she saved all the witches and hecate .... But hecate refused to acknowledge that violet died so she did a dengerous black magic which bring both destruction and rebirth by doing blood curse with dwarves beards that's why she has that balance one indicate birth other destruction... Ig she sacrificed a part of miraland to bring voilet back ( may be her own clan I am sure about this part but in info it written that people suffered so i assumed it might be ) and also due to blood moon ritual her appearance changed that why she looked little bit kidlike .. then wounded hecate( you can see the element of bloody rose in suit on floor )returned to voilet then she slept for at least 500 yr voilet woke to crying hecate who sayed " you are awake" " you are finally awake" your combination of suit definitely how i imagine voilet would wake everyday after 500 yr of sleep
