We all know that World of Warcraft: Chronicle Volume 1 will be out next month, and a preview of said book gave us a lot of interesting new details about Azeroth.
When talking about the Artifact weapons of Legion and the lore that's being revealed for them, Paladin Artifacts are some of the most interesting, touching upon the origin of the Order of the Silver Hand and the fate of Watcher Tyr, the missing Watcher from Ulduar.
Humans in the Warcraft setting have a very distinct origin -- they were created by a curse.
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.
