This new Warhammer Age of Sigmar site is designed as a resource for all fans of the game and setting, with guides on how to play, build and paint, and guides to the worlds and armies of the Mortal Realms.
It even has the core rules of the game, free to download!
The team that they have in the videos work very well together too from what I have seen.
For a person who has their interest piqued with a potential foray into Warhammer, I have to say it seems to be a great place to gain information about the Realms in the Age of Sigmar.
There are videos which add depth to the Realms too.
