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.
In CataclysmThis section concerns content exclusive to Cataclysm.
- There is no evidence or lore explaining the origin of the great wall, but some have supposed that King Thoradin built it ages past during the Troll Wars, perhaps to protect his lands from the trolls' onslaught; note that the ramps on the Hillsbrad Foothills side give defenders access to the top of the wall. It does, however, seem quite unlikely that a wall this massive was built in a single king's lifespan.
- It is unclear why the wall is in ruins, however, one can assume that possibly the local ogre or troll clans, or even the Syndicate, may be responsible. Time may be responsible as well, as the wall has withstood at least both the Second and Third Wars.
- In the Escape from Durnholde Keep event in the Caverns of Time, behind the intact wall is still unfinished land containing only discolored land and deformed mountains, as well as a huge ledge from which one can freely fall to their doom.
- The wall is presumably inspired by Hadrian's Wall, the ancient Roman Empire's northernmost boundary in Brittania (now England).
