A central theme of the Plagueworks seems to be the green liquid plague seen in Warcraft III and classic World of Warcraft, alongside the orange crystallized (gaseous?) plague seen throughout Northrend (mainly Zul'Drak, but there are cauldrons of it all over). It has not been confirmed, but it seems obvious. Should it be noted?--SWM2448 19:18, January 15, 2010 (UTC)

The "orange crystallized plague" in ZD are called Blight Crystals I believe - Siradys (talk) 20:51, January 15, 2010 (UTC)
