I came across this odd scene at the Foot of the Fangs in eq2 zone:Kunzar Jungle. This is north of The City of Mist. This was very close to the eq2 object:odd pile of rocks.
Four dead knights and a dead horse, there was a ghostly round shield floating above the scene but no apparent way to interact with it. I suspect this is a shield quest which, like the Bone Bladed Claymore, cannot be interacted with until you have the quest.
