Demonic Contamination (quest)

Objectives
Thiah Redmane, at the Cenarion Post in Hellfire Peninsula, has asked you to gather 6 Helboar Blood Samples from Hulking Helboars.
 * Helboar Blood Sample (6)

Description
Welcome to the Cenarion Post,. We don't often get company out here, but I'm grateful for the visit. My work with the creatures of this desolate land requires me to travel to many remote places.

The Cenarion Expedition has dispatched me to study some of the most dangerous wildlife in Outland, and I've made a startling discovery. While many creatures here have already undergone radical changes, they continue to mutate. I'm collecting blood samples to document the changes, and any help would be welcome.

Rewards
You will receive:
 * 10400 XP (or at level 70)
 * +250 reputation with Cenarion Expedition
 * +250 reputation with Cenarion Expedition

Progress
Were you able to collect the blood samples?

Completion
Well done,. These blood samples will prove helpful in my research and in the Expedition's wider studies of Outland's creatures.

If I could isolate what causes these creatures to change continuously, perhaps I could concoct an antidote.
