I really don't see why some are so distraught over Wolfe's use of a really big Godling or astral travel. Severian's relationship with the new sun seems equally mysterious. How can a man freely travel back and forth in time just because he has some affinity with a star? without mechanical "SF" enhancement, how does Wolfe really explain Severian's connection? How about silk's auto-resurrection at the end of Calde of the Long Sun? I really don't think that access to the corridor of time is any different than travelling through space with a mental projection. The sorceror in Sword of the Lictor is clearly a psionicist. Is his mental fortitude any different than magic or astral projection? Does a device or genetic alteration allow him to use his mental powers? I don't think so. According to A.D. + D., astral projection is a well established psionic ability, as is conjunction with another mind. The godlings might very well be mechanical. who cares?
