We've had several columns now where we've talked about developing and creating a character -- the basics of story creation, setting up character profiles, and even some of the basics of beginner roleplay.
Lord Darius Crowley likely never meant to be a hero.
All Elves on Azeroth today date back to the ancient Kaldorei who rose to power before the Sundering.
A king in exile is still a king, and King Genn Greymane is nearly the living personification of his lost nation -- at times arrogant, willful, tenacious, and filled with a bestial fury that may be held in check, but never truly leashed.
When it comes to age and timelines in roleplay, there's some overlap with certain races. Humans and worgen go hand in hand, and the Forsaken were also at one point human. This means that when you're considering creating one of these three character races, you can pretty much look to the same timeline -- with a few adjustments for where said character grew up, lived, or died, of course.
