I mean, I've read a lot of CoC stories, listened to a lot of games, and looked at a lot of posts...
and I've never seen/heard of a RP that the characters ran into old squid face himself. I mean, it's always some OTHER unspeakable horror or abomination of time/space/reality.
So, is Cthulhu shy? I mean I've seen the Slenderman games, and you actually SEE (Not for very long) Slenderman himself. You CAN at some point meet Tiamat, Bahamut, and any other God in DnD, why can't you meet the Namesake of the game itself?
