YOU GUYS. Maybe I'm reading too much into this, but... look at this.
Magnum Opus:
MC: It's a work of art. Whoever created this must be a true master of their craft. Sylus: That so? Surely the virtuoso is fond of her magnum opus?
Beyond Cloudfall Ch 4:
MC: You have no intention of disguising yourself? Sylus: No need. No one would believe a fiend would wander around a market. Besides, everyone sees a fiend differently--some see ugliness, others see horror, cruelty… What they see isn't me. They only see their own hearts. I hold up a mirror from a stall. It reflects the face of the dragon. MC: Can you guess what I see when I look at you? He lowers the mirror as if he heard a childish joke. He leans closer. Sylus: At the very least, I'm a lot more handsome than I was depicted in that Fiend-Slaying God mural.
Sylus may be implying that MC is literally responsible for him looking the way that he does. In the main story timeline, Sylus seems to have a stable appearance as we see him through multiple POVs in main story content and World Underneath stories.
It doesn't seem like a stretch that when MC curses him to live on, this curse "locks in" his appearance as... the way she sees him. 🥹
Even if it's not literally true, he knows on a deep level that if she sees him as beautiful, it's a reflection of her own heart. Seeing him how she does? That's her own creation.
I WILL NOT RECOVER.
