By the "core," I meant of the apple she'd bitten. I was going to title it Eve, but I preferred to emphasize the modern-ness of the situation, so I opted for Snow White.
She's fallen and holding an apple, at which I imagine the "swarming creatures" have been gnawing. I am here trying to indicate the length of her having been fallen.
I admit I took "mazy" from Coleridge's "Kubla Khan" (Five miles meandering with a mazy motion / through woods and dales the sacred river ran). Here I mean to say they move deceptively, to try and "trap" people, but also that they move in "mazy" patterns, never truly going anywhere. That they just "pass" is just my way of saying they basically abandon her.
I hope that's a bit more clear. I'm not terribly interested in getting this poem to its 100%, though I thought maybe Serenity would like it, as I had her in mind when I wrote it (and I can imagine her nodding at everything I've said here).
