The Defenders of the Stone are an elite military group of Tear used specifically to guard the Stone of Tear. This is an important task due to the fact the the Stone of Tear holds the Sword That is Not a Sword, the prophesied weapon of the Dragon Reborn. The current Captain of the Stone is Rodrivar Tihera.
Even though the prophecy regarding the Sword that is Not a Sword has been fulfilled, the Defenders of the Stone still stand as the guardians of the Stone of Tear.
Their battle cry is "The stone stands!" Only Tairens are accepted into the Defenders and officers are usually of noble birth.
