Lord of the Rings Online website has a new "Point of Interest", and we're treated to a look at the unreleased area of Forochel, due in Book 13. As this region was not heavily fleshed out by Tolkien, the designers at Turbine had a lot of freedom in creating it.
Although it's undoubtedly very cold in Forochel, we learn that it is still home to many animals, and the Lossoth faction of Men who live off of some of this wildlife. We're also told a bit about Arvedui (seen in a few of the Book 13 screenshots) and his mysterious past -- he'll definitely be worth keeping an eye out for. Perhaps he will play a part in the continuation of the epic quest line?
