When the call to arms was sounded, Garrosh Hellscream was quick to pick up his axe and head for the frozen shores of Northrend along with his fellow members of the Horde. Garrosh's Landing is the name used to describe the place where his fleet first landed.
There appears to have been an entire encampment, judging from the various buildings situated at the site. However, nowadays - a purple fog of unknown origin covers the shore. One rarely visits this place anymore and Garrosh has retreated his forces to Warsong Hold.
