Everyone falling into madness over the Eldritch horror and he can sniff out a tomboy in the middle of that mayhems. Nothing can faze this man.
Eldritch gods are an old fad for old people. They hold no real existential terror any longer with the mainstream topics of the horror genres of today. It looks more like he's asking him to overcome his own existential fears and maintain his own self while not giving into the needless insanity troupe that pollutes Lovecraftian fiction trying to point out the inherent meaningless of man's perception of reality. Don't let the meaningless and unexplained crap that eldritch horror never fully describes create doubt, yet use it to the extent of your current limitations.
I've seen the same thing over and over about the uncaring universe/realms/existence full of beings who don't care if you exist or not. Don't let your mind be consumed by crap that was created to be inherently be unknowable. Understand what you are able to at the time you're are able to understand it without fear and grow accordingly.
