Tol Barad is the name & location of a many historic battles fought between the forces of the Alliance and the Horde over the control Dun Modr region of Khaz Modan and the island of Tol Barad. The Horde was occupied with defending a small outpost in Dun Modr, while Kul Tiras and Stromgarde attempted strike out at the orc raiders from their base on Tol Barad. The Horde successfully repelled the attacks on their base, although the Alliance was able successfully push them back to Dun Algaz at least once.
However the Horde forces counter attacked retaking Dun Modr, and bringing forces to bear against Stromgarde's island citadel of Tol Barad. leaving the fortress in ruins. No life more complex than a few hardy weeds and insects survived the Horde's bloody victory. An aura of death seemed to radiate from the island. ( Tol Barad has become a frightening symbol of the Horde's merciless tenacity and barbarity. )
While the Horde may have initially retaken the Dun Modr, their attack was successful. The Alliance held the ruins after the war, using it to stage attacks on orcs in the region ( but later lost it the Dark Iron dwarves. )
