Is there a FAQ? I think we need one for some important plot points such as "Who is Severian's mother?" and "Who is Dorcas?" and "Who is Severian's Father?"
A completely unrelated point: Do you believe the wounded soldier in CotA is really Jonas returned? Severian thinks so, but that doesn't mean that he's right. I just never found Sev's reasoning very persuasive.
