Two Naga witches have been masterminding the assault on this outpost. They've repelled direct attacks from some of my best grunts, but you can finish the job where others have failed.
Seek out and slay Lady Silisthra and Lady Vesthra at the eastern edge of the cliffs, around the ruins of the ancient night elven colossus. You will first need to destroy the powerstones that give them their strength. Do not disappoint me, <class>!
Now THAT is how we used to handle serpents back in Durotar - we crushed them under our boots! You have done the Horde proud, <name>. As soon as my reinforcements arrive we'll mop up the rest of those vermin and claim this peninsula once and for all.
