So what? Makes for more interesting opporturnities. Was kind of a joke though; I don't really care what Ordo Inquisitor we work with long as it isn't Malleus because, well, at least in my head-canon, daemons are too serious a business for ordinary sororitas to handle, even though the are awesome.
While a Greater Daemon may be a bit much, I like the direction. Maybe something a bit lesser, like a recently ascended/ascending Prince, or something intermediate like a Charnel Daemon.
