Great Wall, also known as "The Wall" is a location in Of Orcs and Men.
The wall was built during the years of war with the Orcs to protect the empires citizens and territories from the "orcish threat".
This was done with the help of countless orcish slaves, many of them losing their lives in the process. Their mortal remains can still be found in the sewers and tunnels running below the Wall.
These Tunnels are inhabited by all sorts of people and creatures, like Thieves, Bandits, Beggars, Goblins and many more.
