Then Severian gets =off= the ship, spends a short amount\nof time (a local day or so, iirc) on the world/ship Yesod, and then, from\n=within= the world/ship Yesod (which might be another universe alltogether,\ni.e., \"Abaddon\") Severian is teleported (simultaneity) to Briatic space,\nnear enough to the Ship to be drawn onboard with a life saver.\n\nHe did not get back onboard the Ship in Yesod space.\n\nThe 1000+ years of time reversal thus happened during Severian's stay on\nYesod world/ship (perhaps time flows backwards in Yesod space; or maybe\ntime flows backwards only within the world/ship Yesod).\n\nWe don't really know what the experience on the Ship travelling from Yesod\nto Briah is like.  If it is a mirror image of the trip from Briah to Yesod,\nthen perhaps it sails to the beginning of Briah, which would be something\nlike the Big Bang. (The big problem is that time dilation is a one-way\nstreet: Ship is still moving into the future only, unless Yesod space has\nsome sort of reverse-time aspect.)\n\nBut Severian has to get to Urth within a very narrow timeframe.  The Old\nAutarch, who failed the test quickly, seems not to have gone into the\ninterior of world/ship Yesod.  He presumably departed on the Ship and\narrived back on Urth within a few months or maybe a year after his\ndeparture (again, time dilation is a one-way street).\n\nNot so for Severian.  He is cast into Briah space at a point 1000 years\nbefore his own time, and picked up by a Ship that had not met him yet.\n\nIn short: teleportation again complicates the picture. <g>\n\n(Ossipago, Barbatus, and Famulimus use a time saucer, so time-machines are\npossible.)\n\n=mantis=\n\n\nSirius Fiction\nbooklets on Gene Wolfe, John Crowley\nhttp://www.siriusfiction.com/"
