When Does "Madame Xanadu" #1-#2 (2008) Take Place?
"Madame Xanadu" #1 "Chapter the First: By the Runes" to "Madame Xanadu" #2 are historical fiction fantasy comic-books written by Matt Wagner that premiered June 25th, 2008. So when is "Madame Xanadu" set?
It takes place on the fictional DC Comics Universe timeline in the year:
We know this because "Demon Knights" issue #1 includes a "Prologue" that begins with free-floating text reading "Four centuries ago. The last night of Camelot." and the rest of that issue takes place in 1013 AD. (Camelot is the quasi-historical British capital under the legendary British King Arthur, who may or may not have lived in the real world at all.) Conceivably, this loosely puts "The last night of Camelot." sometime around 613 AD and this entire issue takes place in this setting.
1,013 - 400 = 613.

It is a chronologically early comic in the DC Comics Universe multiverse timeline (a first chronological story to feature Nimue Inwudu/Madame Xanadu) and can be read at its timeline point or as an extended flashback.
