"The third part opens with the Nameless Hero and his friends sailing to a new continent overrun with orcs, arriving in the Myrtana, the central region of the continent. The hero lost all his stuff from the previous game when his ship is stolen while he's onshore with Milten, Diego, Gorn, and Lester. These lands have no physical connection to Khorinis or the ruins of the penal colony. In these mountainous forests the orcs have enslaved the human kingdom with only a few free humans living in the nearly uninhabitable icy northlands of Nordmar and the southern desert of Varant. The hero must decide whether to join the rebellion and stay true to the deposed human king, serve the Orcish usurpers in their quest to topple the last remaining human stronghold, or choose a path that serves his own ends.
