If you've gone through the Book 10 epic quest line, you'll know Amarthiel well. She's the sorceress with the palanitr you had to track down with the aid of crazy Sara Oakheart. The three screenshots provided show a new and improved Amarthiel in all her megalomaniacal glory.
The housing decoration options shown in four of the screenies are the new trophies that will be dropping from Middle-earth's boss mobs in Book 12. These trophies can then be displayed in the players house or, more likely, the Guild Hall. We can see so far a mannequin holding up a suit of armor, two swords mounted on a wall, an outdoor trophy in the shape of a monument and, finally a head on a pike (or the Elven babe lounging on the bed, we're not sure which one is the prize).
The new cosmetic outfits that your character can put over their battle gear are also on display in six screenshots. They spotlight many different races and classes and now they no longer looking like patchwork dolls. Some of these new clothes will be crafted, other items can be vendor purchased. If you look closely at the the picture of the Elf outside the Guild Hall, you'll see one of the new quiver models on his back.
When this patch goes live it will only be a matter of time before we see the first screenshot of a raid party confronting the Balrog in pretty pink dresses.
