When it dawns on you

"... wait a minute ... this sixteenth-century Chinese author just described a brain tumor, after a Taoist healer's method!"

... I'm kind of an overwhelming nerd. Anyway, I realized that I'd almost let Sheptember go by without being properly narcissistic about it, so here's a picture of that main fursona I never seem to draw much.
If you're curious, I'm referring to Luo Guanzhong describing Cao Cao's death in the novel Three Kingdoms. The physician called in to deal with his migraines and hallucinations even goes so far as to recommend brain surgery only to be rebuffed and executed by Cao Cao, who thinks this whole "cutting his skull open with a cleaver and removing a portion of his brain" thing has to be some kind of murder attempt. Not like I blame him.
