HBO’s released character posters for Season4 of GoT

What’s the meaning of all of this? It’s driving me crazy!!

They released 18 posters of GoT characters with the quote: “Valar Morghulis”, meaning : “All men must die.”

You no noffin'

But really, what are they implying?
Also, why so little love for Hodor?!
Yep, he’s the best and definitely should rule the 7 kingdoms.

Valar Hodoris.
