Shadow's Martial Arts is the building that is used to cover up the League of Shadows activities. Underneath the building is a labyrinth of tunnels that houses the elites of the League. It is the home of "The King" and many of his lieutenants, along with his best fighters. It is also a training ground for new recruits to the cause, which helps with the cover of a Martial Arts Studio.
The Dojo is split into two parts. There is a wooden floor for most training but there is also a red and blue rubber-like material that is used for the rougher training. This is open to the public and takes up most of the building, except the office, bathroom, and private office (where the entrance is hidden).
