How fortuitous it is that the Ruby Dragonshrine lays just to the east. It is there that you will find a flower called the ruby lilac. This lifegiving plant is all that I need to concoct a vaccine for the untainted beasts of this region.
Travel east and search the Ruby Dragonshrine for the lilac.
Just one thing: The dragonshrine, like all the dragonshrines in this blasted wasteland, is beset by the Scourge. Watch your step. We wouldn't want you to be devoured by an emberwyrm.
Do you have the ruby lilac?
That wasn't so difficult, now was it?
Now give me a moment to prepare the vaccine.
