I just wanted to say that after picking up Mystery Cults and playing a Criamon magus for a while, I really like the new take on House Criamon. I can spew off mystical "nonsense" that makes sense to me while sounding totally insane. I am interested in specific things, the SG knows just what to put in to pique my interest. And all this flowing from the House's description.
I've not played the character for a lot of time (some 5 sessions, two seasons in game-time). I've yet to interact witth the House, and other Criamon magi. But so far, I'm really enjoying the ride.
Having no knowledge of Criamon in previous editions, I must say I enjoy them in 5th. Bolth their philosophy and methods are quite pleasing to my tastes.
