Wake of Destruction

Our time here draws to a close. I must somehow follow the trail of these naga captives if we are to discover their purposes in this region. But before I move on, I would see the destruction of this operation! Nevermind their numbers, I have a plan that has the potential to even the odds. Outside this cave, famished great sharks, displaced by these naga, seek food. In their weakened state, they will be susceptible to suggestion. Use this orb to subdue them, then direct them against our enemy.
