I have mentioned before that I don’t know where the ideas come from. Sometimes they slowly bubble their way up out of my subconscious. Other times they spring forth fully adult, like Athena bursting from the forehead of Zeus. (I know that’s Greek, not Norse, but I couldn’t think of a Norse example that fit as well.) The idea for this mashup sprang forth fully formed and I know from long experience that when I get an idea like this, I have to draw it to get it out of my head. Good grief, indeed.
