Helping the Cenarion Post (Horde)

Objectives
Falconer Drenna Riverwind wants you to offer your services to Thiah Redmane at the Cenarion Post in Hellfire Peninsula.

Description
, there's some tauren by the name of Thiah Redmane that keeps pestering us for assistance. She's with the Cenarion Expedition, and they've setup a little post just to the west on the south side of the road leading to Zangarmarsh.

If you hit Thornfang Hill, you've gone too far.

Do you think you might head over there and see what she needs? I don't want to have to bother Ranger Captain Venn'ren with such trivialities.

Rewards
Upon completion of this quest you will gain:
 * 975 XP (or at level 70)
 * +10 reputation with Cenarion Expedition

Completion
Oh, goodness, you must be the help I requested weeks ago from Falcon Watch.

Well, you're here now and there's a lot to be done. I have just the thing to start you out.

Progression

 * 1) Helping the Cenarion Post (Alliance) / Helping the Cenarion Post (Horde)
 * 2) Demonic Contamination (quest)
 * 3) Testing the Antidote
