Into the Temple A is bugged. Quellious does not respond to discreet. So you can not start the flagging process to get into the other areas of the Plane of Health.
Might want to include your server and the exact dialog you are getting from hails and your exact responses. I've not had any issues with this lately (within the past 2 months).
Are you at least level 75? Are you invisible? If you have done it before it's not repeatable. I'm not sure if I remember this one being finnicky if you dont use the [links] from the on hail, hail her to see if she gives you and then click [worries], then click [discreet].
I did it on a level 75, got it, finished it, and got no Remnants. Same with Seal of Approval. If there some flag I need? I did it with lvl 100 heroic and got the remnants np.
