Silence Their Cries

The weak-bloods, defiant unto the end, will continue to fight and die until we wipe them out. They look to the horizon for reinforcements that will never come, and persist in bearing arms against their rightful conquerors. Ellyrian Reavers and Defenders skulk throughout Tor Elyr like whipped dogs, baring their broken fangs at any who approach. Go to the fallen city and teach these curs that their resistance is futile! After you have exterminated these vermin, speak with Deridian Gor. He will give you further instructions.

Travel to Tor Elyr and join in the slaughter of its High Elf defenders. Kill Reavers and Defenders, then travel to Conquerer's Watch and speak with Deridian Gor.
