These are a few comics that take place in "The Past" whatever that means. They're a little scattered. Shædo and Shiné appear as children. There are also a pair of black mages from Fallenhal and Moncrefe, as well as a contract abductor who tries to capture the Moncrefe black mage, but nothing got far enough with that story to tell the reader anything substantive.
How mysterious. Well let's go back to the other comics.
