Sword of the Lictor, chapters 1 to 4
And we're back! Severian is Lictor of Thrax. Dorcas goes missing in the city and when Severian finds her again she is unable or unwilling to speak. Meanwhile, trouble is stirring in Thrax, and the Archon is requests Severian's attendance at a gathering for the great and good of the city- though suggesting he is likely to have to work while there.
(*) Thrax is given an interesting description. It sounds like it's built into a hydroelectric dam.
(*) Severian's speech to Dorcas, justifying his profession, sounds more like he's trying to convince himself.
If I can forget some of his previous thoughts and actions, I feel I almost like Severian in these chapters. Based on the last time this happened, he's probably about to do something awful.
