Raj Naz'jan was the emperor of Riplash when Leviroth was imprisoned. Azshara herself blessed his trident so it would slay the beast should it ever escape.
Now you wield it, <race>. As much as it disgusts me, I will have my revenge on these barbaric giant-men.
Take the trident to the depths beneath Riplash. You will find Leviroth slumbering at the bottom of the sea. Drive the trident deep into his flesh! Return to whomever sent you when you're done; I wish to see no more of you.
