This story has been singled out from the continuity for one main reason: while the continuity is listed in chronological order, "Things Past" is the true introduction to the series. For anyone who has not read these stories before, Lex recommends that they read it first. And take it from me, it is indeed helpful. It tells of Lex's mysterious heritage and how the truth is finally revealed to the Wyvern clan. From the Gargrave Saga.
