Thoradin's Wall is a huge wall separating the Arathi Highlands from Hillsbrad Foothills. The wall protected Stromgarde and the Arathi Highlands from the invading Scourge. Thoradin's Wall, an immense edifice on the northern border, was once a symbol of humanity's strength and defensive might. Now, the wall has fallen to decay and war. It is collapsed and gaping wide. In World of Warcraft, the gigantic wall is heavily damaged. In the Escape from Durnholde Keep instance of the Caverns of Time, the wall is in considerably better condition, but still quite a bit damaged.
