Gurky made some new friends at BlizzCon. One of them is all business, the other is more of the wild child of the group.
Do we know the timeline for Gilneas? I play on an RP server and am heavily into the lore but I'm having trouble figuring out how long the Greymane wall has been up and also how far in the past that worgen players will be during the first few levels. The little movie they showed at BlizzCon shows the moon changing by what looks to be about a week and a half, so does that mean the human-based events take place that far back before the launch of Cata, or are we looking at months?
The Greymane Wall had been up for roughly 25 years, give or take a year or two, prior to Cataclysm. The opening events in Gilneas originally took place one year before Cataclysm, but now the length of time is indeterminate -- Blizzard removed the "one year later" reference some time ago.
However, in order for the timeline to make sense, there has to have been time for the Scythe of Elune to be rediscovered in Grizzly Hills and moved. You can assume that your character has had around a year to run wild while the Gilneans set up their worgen hunts.
Once you've got your human mind back, it's mere days or hours before the cataclysm officially hits.
