OK, so I was just reading the comic that xfamily uploaded called "Many are the Helpers of Maria" at
I'll bet the "Katherine" part comes from her delusion of being guided by Catherine czarina of Russia (see page 4). Then page 5 instructs us that the somewhat odd-looking "Rianna" (anybody have an idea from the picture who this is supposed to be?) along with General MacArthur and "Tory" (again, I say, WTF?) are devoted to her.
