See Raptor - broken quest, in Quest for Undefined.

See Raptor, a quest in northern stranglethorn is broken, and cannot be completed. This is for the alliance version, I haven't tested the horde one.

This quest requires you to talk to Priestess Thaalia and go on a "Mind Vision". This is a scripted sequence where you are a baby raptor in zul'gurub, and follow Bloodlord Mandokir around as he gives some exposititon.

You are teleported into Zul'gurub, but you do not become the raptor. Bloodlord Mandokir is not present.
Following the route taken in the quest and wandering around the quest area did not seem to do anything, there seems to be no way to get credit for the quest objective at the moment.

The area also looks to have the NPCs for a later part of the quest chain "Be Raptor" present instead of the setup for "See Raptor".
