Testing an Enemies Strength.:

Search Orgrimmar for Ragefire Chasm, then kill 8 Ragefire Troggs and 8 Ragefire Shaman before returning to Rahauro in Thunder Bluff.

Rahauro: Beneath the city of Orgrimmar, stout creatures known as troggs started coming to the surface from deep below the lava filled tunnels. In her ever-benevolence, Magatha sought to make peace with the creatures, but they turned on her diplomats, killing them. She will not allow such treatment of the tauren people and now consider the creatures a threat to all of the Horde.

She asks that you put an end to this trogg threat before it overwhelms the Horde from below. Find Ragefire Chasm and destroy them all.

Rahauro: How goes your search for the Chasm? And the troggs?

The threat cannot be allowed to persist--it will only injure our orc brethren if it continues.

Rahauro: I am glad to see you took Magatha's task seriously. Thank you, Rawr. I'm sure the troggs will have a harder time coming to the surface with their numbers so greatly reduced.

Perhaps in the future we can take time to figure out where such creatures came from, and what they really want.
