Miles off the coast of Westmarch lies an island that many believe to be little more than legend. Cut off from the rest of Sanctuary’s developed civilizations, '''Greyhollow'' was once the center of a grand empire. Often times, such isolated societies grow and advance at incredible rates, and Greyhollow was no different. Its citizens devoted their cause to a mysterious and, as is often the case in Sanctuary, completely evil being. For reasons still unknown to this day, this unimaginably advanced society collapsed, leaving ruin, chaos, and a lingering curse behind.

Greyhollow Island only appears in [[Adventure Mode]] and does not tie in with the existing Diablo III story. Seven [[events]] will help that story unfold. There will be exclusive monsters and bounties in the area too.
