Report to Nasuun was part of the Shattered Sun Offensive storyline. This quest was made available to players once they have recovered the Sun's Reach Sanctum on the Isle of Quel'Danas. Once players have activated the Sunwell portal,  replaced this quest.
My liege lord, Exarch Nasuun, is heading up the Offensive's efforts to do just that. He asked me to send along any promising candidates who have what it takes to help with the portal's creation.
Please, travel to Shattrath City and speak with him inside A'dal's chamber on the Terrace of Light.
Portanuus sent you? Good, we haven't any time to spare!
