From the shadows, brother <race>, I bid you greetings.  I am to serve as your coordinator for our plan to sabotage the Scourge's cauldrons.$B$BOur goal will be to change the composition of the plague that the cauldrons create into something that negatively affects the Scourge.  In order to affect this change, you will need to secure access to each of the four cauldrons here in the Western Plaguelands.$B$BThe time has come for you to lead the charge against the Scourge, hero.
