Reader Deckard points out the "A" in Drake symbolises a pyramid with a capstone in the middle.
Shaving the eyebrows off is symbolic of removing your eyes, since "brow" can mean "twinkle", "blink" etc. so I also suggest along the same lines, the "A" is the eye of Horus. And a singular eye at that.
Drake, the author's name, actually means "dragon!"
WILL RISE TATTOO? Will Rise? William rise? Dragon Will rise?
Many thanks to Deckard!
