I logged onto my freshly 85 Paladin last night, and just as a do I saw, what looked like, an NPC "Suspicious Character". He was hiding behind the General Goods Vendor in Nordrassil. He looked like a blood elf and was red but didn't appear to be attack-able. As soon as I tried to click on him he vanished.
I asked the guild about it and no one seemed to have any input. Then I searched the forums and didn't see anything.
Anyone know anything about this? Part of a quest or phasing? Maybe pre-MoP things happening like the earthquakes before Cata?
