That wound on her looks QUITE like a stab wound. But I wanted to find a different interpretation of a stab wound. Especially when I can't use -1/-1 counters in this set, and the original design already does such a great job at evoking the feel of a stab wound while still being New World Order-friendly (New World Order is the name for the current age of modern design principles/rules).
I looked at the blood and noticed how it was black. ...Seemed magical, then. Otherwise, she'd have red blood, right?
So that's when I thought, "Aha! What if the lady wizard being depicted here isn't a creature - what if it's the player herself?" That would explain the painful, magical blood.
