The Orb of Command is only usable if one has completed the quest , the attunement quest for Blackwing Lair. In order to gain this quest, you must kill the Scarshield Quartermaster between the Blackrock Spire instance portal and the Orb - protected by several Scarshield warriors - and gain a copy of Rend Blackhand's instructions. Once this quest is attained, you must enter Upper Blackrock Spire and kill its dragon lord, General Drakkisath. Directly behind the General is a glowing orb known as Drakkisath's Brand. Touch Drakkisath's Brand and you will be given the "Mark of Drakkisath." Once you have the Mark of Drakkisath, you are attuned for Blackwing Lair and can enter the instance using the Orb of Command.
