Ending the plague
So for those of you who haven't been online for a while, or who don't have Horde characters in Outlands, or who just haven't been to Shattrath for this...the plague has ended, and this is part of how it did. Grand Apothecary Putress asks you to deliver a dual-plagued brain to his associate in [your race's capital here]. The brain whispers to you. This brain not only has the plague, but also an anti-plague, and they're fighting, and this is how the cure is supposed to come about.

If you've seen or read or heard spoiler-rific things, you know who Putress is by association.

If you've paid attention when questing Horde-side in Thousand Needles, you may have wondered about the coincidental nearness of Grimtotem to another group, and suspected an alliance.

If you've done both, then the fact that Putress's associate is standing next to Magatha Grimtotem will mean a lot to you...and if it doesn't, I won't spoil.

But seriously, though, this quest was creepy and...yeah. I'm not sure I really want to gain rep with this faction. The quest text just screams WARNING to me.
