“Welcome to The Elder Scrolls Online v2.04 and our next Chapter: Greymoor! Explore the icy mountains and wild forests of the Nords as you venture forth into Western Skyrim. The land is harsh and unforgiving, much like many of its people and its lords. High King Svargim welcomes you to the capital city of Solitude gruffly, but youll have the opportunity to earn the respect of the Jarls and the swordthanes of Western Skyrimif you survive.
In addition to climbing over the frozen peaks of Western Skyrim, youll have the opportunity to delve into its darkest ruins and greatest secrets. Find the hidden entrances to legendary Blackreach, the subterranean realm beneath the lands of Tamriel and explore the darkling caves and forgotten ruins deep below Western Skyrims surface. Two wildly different lands, stacked one on top of the other, each threatening and threatened.”
