Karabor Training Grounds

Our scouts have reported a massive influx of Sunfury blood elf recruits heading to the Ruins of Karabor. Normally this would represent a purely military threat, however we believe something else is amiss. Descriptions of their attire and fighting style are suspiciously close to that of Illidan himself. I do not want to become alarmed without good reason, so I would like you to go there and bring me back their weapons. We will then determine whether my fears are unfounded or not.
