A Shadow over Akeroth
The Vankin Mountains in Kul’Adar stand as the the most Northern point accessible. When the Cataclysm consumed Ishtar and formed it into the Blood Sea. From this Cataclysm everything North of the Vankin Mountains was obliterated with the Mountains themselves taking the impact and saving the rest of Kul’Adar and Akeroth from the desolation of the Cataclysm.
Since the Cataclysm no one had ventured past the Blood Sea or the Mountains and returned, it is because of this that almost everyone believes there is nothing past these points and all that lays past that is The Desolation.
The Vankin Mountains are incredibly large mountains reaching a height of up to thirty-thousand feet.
