Item from Hollow Knight by Team Cherry
Three masks, three sleepers, three sacrifices — the locks on the Black Egg that kept the Radiance imprisoned and the cost of breaking them.
The three Dreamers — Lurien, Monomon, and Herrah — entered eternal sleep to maintain the seals on the Black Egg. Each seal is maintained by the Dreamer's continued slumber. Breaking a seal means killing a sleeping person — ending their life to open a prison. The moral weight is different for each Dreamer. Monomon wanted the seals broken — she left Quirrel's mask as a key. Lurien would have chosen to sleep forever out of loyalty. Herrah bargained her sleep for a child, not for philosophy. The game asks you to break all three and never tells you if it's the right thing to do. The seals are the Pale King's final contingency — his admission that the Vessel alone wasn't enough. He needed three more lives to make the prison hold. No cost too great.
Three masks adorn the Black Egg Temple: Lurien's single-eyed mask, Monomon's smooth oval, and Herrah's angular spider-face. Each glows faintly. When a Dreamer is killed (their sleep ended via Dream Nail), their mask cracks and falls from the Egg. The visual is deliberate — you are destroying something sacred.
