Blizzard clarified why the Scourge Invasion began today on US realms ahead of schedule.

This was a surprise to us, but all in all, a welcome one.

We previously believed that the Scourge Invasion would start 168 hours after the Zombie Plague. That’s why we used the dates we used in our posts about these events. Nonetheless, a trigger for this next set of conditions fired off at 72 hours, which was earlier today for all realms in this region.

With one exception– Eranikus. Because Eranikus was just opened new a couple of days ago, and we wanted players to move to the realm and get started without too much interference, we’ve kept the Zombie Plague off there for the time being. We’re planning to skip the Zombie Plague altogether and initialize the Scourge Invasion on Eranikus soon, perhaps as soon as this evening.

Overall, we like getting the Scourge Invasion started as soon as possible, since all of its challenges and unique encounters will go away when Northrend opens at 3:00 p.m. PDT (6:00 p.m. EDT) on September 26. (That’s 8:00 a.m. AEST on September 27 in Sydney, by the way.)

Say hi to Prince Tenris Mirkblood for me.

In the EU region, the Zombie Invasion will start on Saturday (September 10) at 03:00 AM.
