"Sure, the Wardens are quite useful if Outland were to be invaded by a wandering kobold. But when an army of thousands of Savages comes screaming through the Mists, who are they going to call?"
Knights of the Guardian Hawk are the organized defensive force protecting Outland. Where the Border Wardens are individuals, the Knights are a large army of trained fighting men, garbed in plate mail and usually mounted on mighty steeds. These knights are stationed in the Unsleeping Guardian Keeps, which protect the only passes through the Savage Fang mountains into Outland.
