Though we've speculated time and again as to the origins of the worgen race, and we know for certain now that these worgen were at one time night elves, worgen history itself has been somewhat shrouded in mystery. The druids responsible for the worgen curse -- Druids of the Pack -- were deliberately using a druidic form that was forbidden to the night elves. So why would they choose to use it? What kind of situation would require defying Malfurion Stormrage's orders?
More importantly, we have the case of the Scythe of Elune, an artifact that has been referenced here and there since the early days of vanilla, where both Velinde Starsong and Arugal were tied in to the Scythe's unusual history. But where did the Scythe come from originally? What makes it so peculiarly special? More to the point, how on earth did the worgen get into Gilneas? Interestingly enough, everything ties together -- from the Scythe to the origins of the Druids of the Pack to the unfortunate fate of Gilneas.
Please note: Today's Know Your Lore contains spoilers for the five-issue miniseries Curse of the Worgen -- an excellent series that I highly recommend people pick up. If you do not wish to be spoiled, turn back now!
