Where To Start “Continue the Guardians of the Dream Campaign" in 10.2.5?

I have no idea where to pick this up.

This really should be skippable, especially considering my alt has already been to ED a couple of times and has completed all the quests there. But now he can’t finish the weekly Aid quest because this is hanging open and I can’t figure out how to do it.

[NOTE: Finally figured it out, somehow. But no thanks to the design and no thanks to the changes brought by 10.2.5 to the Emerald Dream.]
