That's not really the kind of thing that happens. The Liminal City has its own sort of time: think of it as complementary to Eternal. Instead of all times always being Now, forever, all times are always Yesterday, forever. Inhabitants who come there after dying on earth are still on their own timelines. For one it's the day after October 19th 823, for another the same day in the Liminal City is equally the day after January 21st 1985. But for people like Dahlen or Apzides, who are part of and have never been anywhere but the Liminal City, every day that they've lived there is yesterday, it's just that all but one of those yesterdays is also yesterday to an increasing number of those other yesterdays. Which is all to say: if it's possible, it's never happened.
