Spoiler alert: This post contains fairly heavy lore spoilers for the Cataclysm expansion. If that's not your thing, you should stop reading now.
In Cataclysm, during the quests in Silverpine Forest, Horde players learn that human refugees from Hillsbrad have fled to Fenris Keep, and our glorious Banshee Queen Sylvanas sends us with a loyal val'kyr to kill and raise the poor humans as Forsaken, to bolster their forces in Silverpine. Using the new on-the-go questing feature, Sylvanas informs players to find and convert the human leaders inside their keep.
This is when things get a little hairy, as the keep is guarded by elite worgen guards. Battling through, the players find themselves arriving at the middle of a meeting between the big names of Southshore and Lord Darius Crowley.
Darius makes an offer to the humans: They can fight the Forsaken as humans and when they die, they will be reborn as their enemy -- or they can drink his blood and turn into a worgen, who are immune to val'kyr necromancy, and serve him.
The humans aren't excited to be either of the two, but they decide fur is better than rot. Right before players' eyes, we see them drink a shot of Darius' blood and transform into worgen. Through quest text, we are led to believe that every human in Lordaeron was given the same offer, and the vast majority, if not all, accepted.
This is a pretty big deal, and I'm surprised I haven't seen more talk on it. The worgen have a stable way to produce more worgen, other than normal procreation (if that works). If this works for all worgen, could we see some extremist/fringe worgen groups akin to the Forsaken, who want to see all humans cursed like they are? A few vials in a few kegs next Brewfest could cause immense havoc. Mage water suddenly looks delicious for your run-of-the-mill human.
What do you, dear readers, think of this? Will it work with all worgen? Or will this ability be misused by the worgen? Next patch, will we see a red "plague" canister model in Gilneas, complete with a Royal Blood Society (to use against the Horde, of course)?
