If you haven't read the books yet these names might not mean a whole lot. But it's good to know they will be cast for season 3. Most of them should have already been introduced but as the creators said there are only so many new faces they can throw at the viewer in one season.

I am happy to see that Robb's maternal relatives will be cast as they are really critical to some things which already took place and some things which have yet to occur. shhh

Season 3 Casting

Quote:
EW.com has a list of new characters coming to HBO’s Game of Thrones in season three. Fans have been wondering which names from George R.R. Martin’s third Song of Ice and Fire novel A Storm of Swords will be introduced next year, especially since the lengthy book is being divided into two seasons.


"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
