Mantis,
If there's room on the train, I'd like to refine my initial question about Quetzal's motives to: What was Quetzal's motive in wanting a thriving human colony on Green? Thanks again for this chance at getting some concrete(?) answers from the man himself, Vance P.S. Someone--PLEASE--ask what, specifically, was the ghost of Pike, which Silk saw in his manse.
