This novella inspired Tomasz Bagiński’s Oscar-nominated short animation

Planetoids in the Lévie star system. An accident forces the “Sagittarius” towing craft to seek shelter on one of them. There is however not enough oxygen for all of the people on the craft. Izmir Predú sacrifices himself to save the rest of the crew.

Years pass by and pilgrims keep visiting his grave on the cold, atmosphere-less planetoid. Do miraculous healings really take place there? One of the convalescents founds a church made of crystogen built over Izmir’s grave. But you don’t use crystogen to build with, you plant crystogen – it combines nanotechnology, organic biology and evolutionary algorithms. Therefore the Cathedral grows, matures, blossoms. It’s alive and dead, it’s a building and an organism, it’s a work of art and the act of faith.

Father Pierre Lavone arrives on the planetoid to valid ate the rumours about  Izmir Predú’s sainthood and his miracles, before the planetoids, and the Cathedral with them, disappear forever in the interestellar emptiness.
