Marvel.com: What are the most important things that a reader should know about Lady Sif from the get-go?
Kathryn Immonen: She jumps first and she doesn’t look to see if anyone is following; if they are, great, if not, more for her. She’s fierce and loyal and wants to serve her people above all.
Marvel.com: How does Sif see herself, despite what the truth of the matter may be?
Kathryn Immonen: I think that there’s some element of blind devotion in her character; devotion to her cause, to Thor, to Asgard. And that’s admirable but it’s also one hell of an Achilles heel—Hey! Mythology!—because it can make you think that everyone is playing by the same rules, your rules.
Marvel.com: What kicks off her quest for an ancient Berzerker spell in JOURNEY INTO MYSTERY #646?
Kathryn Immonen: At the end of Everything Burns, Sif is sick at heart that her homeland continues to be attacked, that Asgardians continue to die—and this is not necessarily specific to Everything Burns; it’s practically a leitmotif. And she finds herself thinking that Asgard should be so strong, so powerful that that, in and of itself, would be a safety mechanism. It’s a theory of a build-up of arms as a preventative measure that is as old as anything. [In the real world] Richard Gatling turned seed broadcast technology into a gun that he was sure would act as a warfare deterrent; Sif, as is her way, takes it upon herself to test this theory.
