CW: No spoilers, only what we’ve already seen in this manga so far
Theory: So Esther (The hero; also Riveni’s mom) is immortal and has been creating homunculi over the past 300 years to revive Lynn cuz she probably is in love with him. and the immortality spell probably was some black magic too. (shes also the only one who cried in chapter 1 when he got put under the ice like cap’n murica 300 yrs ago)
But all of the vessels Esther’s created so far are the Hollow Knight (imperfect vessels)cuz the TVA is actively preventing them from defeating the Radiencecuz the intended timeline has Lynn reborn in his current body. Thus leads to mommy issues and black magic. Old guard of Riveni’s may also be an earlier spawn that was also an imperfect vessel.

Literally chapter 1
Nah, 'Mother''s clearly gotta be Tureina, Lynn's disciple.CW: No spoilers, only what we’ve already seen in this manga so far
