Iimmi recited:

"Change is neither merciful nor just.
They say Leonard of Vinci put his trust
in faulty paints: Christ's Supper turned to dust."

"What's that from?" Geo asked.

"That's one of my bits of original research," Iimmi explained. "It comes from a poem dating back before the Great Fire."

"Who was Leonard of Vinci?" Geo asked.

"An artist, another poet or painter, I suppose," said Iimmi. "But I'm not really sure."

"Who's Christ?" Urson asked.

"Another god."


There were more rocks now, and Geo had to brace his stub against the walls of fissures and hoist himself up with his good hand. The igneous structures were sharp in his palm.
