Unmasking the Enemy

I have promised you Ridaran's death, and you shall have it, but not quite yet, Uruin. There is another matter which, I believe, will benefit greatly from your presence. The Shining Guard are dispatching another regiment from their warcamp in Caledor. One has to admire their determination, flawed though it is. You will command our forces during the attack. Once you have exterminated the last of them, report to our main warcamp for further instructions.

Use Zephyr to send a message to your allies in Caledor in order to warn them of the impending attack. Once Zephyr has flown away with your message, make your way to the ambush location and ensure the Dark Elf plot fails. Finally, make your way to Asuryan's Reach on the Stonesong Plateau in Caledor, and speak with Erindrel Quickleaf.
