Abbie's symbol thingy is an upside down angelic rune from The Mortal Instruments, I'm sure it's been used before then, every time I see it that's all I can think about.
@paranormalcy it's actually a Nazi symbol derived from the Othala rune (also called Odal). The original rune means "inheritance" or something similar.
