If Phantom is a Lucifer allegory, then Lace is an Adam allegory in every sense of the word. She’s Grand Mother Silk’s favorite creation, much like how Adam was once God’s, and both were born to be loyal to their creators. Neither God nor Silk had the kind of parental relationship an earthly parent would have with their children, opting instead for the kind of unfathomable love a creator shows their creations. Some less than professional schools of thought think this is more than a worthy substitute.
Adam fell into temptation and rebelled against God by listening to Eve, who herself had listened to Satan’s seductive half-truths, and partaking of the fruit of the Tree of Knowledge of Good and Evil with her. Despite bringing sin into the world, God still loved His creation, and made Himself man to die for our sins to save His creation from eternal separation from Him.
Lace fell into temptation and rebelled against Grand Mother Silk by growing jealous of Hornet (whose cloak is apple red, may I add) and making attempts on her life every chance she gets, culminating when Hornet sets off the Void Snare. Lace swoops in and slices Silk’s arm off, freeing Hornet from her grasp and dooming them both to the Void. Despite this betrayal, Grand Mother Silk still loved her creation enough to sacrifice the last of herself to save Hornet and Lace from the Void’s clutches, leaving herself to die.
Both Adam and Lace had plenty reason for their vices to torment them until they couldn’t take it anymore. Neither had a parent who could guide them to a better or healthier alternative. At least Adam had Eve. Lace just has her silkflies.
