Orders from Azshara

This medallion is inscribed with orders commanding the naga to invade our shores and seize artifacts of power. <Kojo studies you thoughtfully.> I've heard tales of a priest who used a horrifying dagger to fight the Burning Legion. It is said this blade... Xal'atath... whispers secrets of the deep. It might be our best chance of uncovering what the naga seek. I'm told the naga have an altar on an island in Stormsong Valley. If you take Xal'atath there, the dagger may reveal crucial information.
