After I first read it I kept thinking to myself, LA-S is awful, why do I like him so much... and then it struck me :D

I would certainly like to hear more about Sylvia D'Agostino! And hey, we don't know for certain that she is one of Piranesi's Dead, only probably—she might be alive and off exploring the wider magical world somewhere, for all we know...

I hope you enjoy re-reading the ending!
