Or, so it would first appear in the recently released expansion pack to Command and Conquer 3: Tiberium Wars, Command and Conquer 3: Kane's Wrath. The game takes place shortly after the second Tiberium war and leads up the events experienced in Command and Conquer 3, following the growth of Nod and the return of Kane.
With this release, the Command and Conquer universe mythology has probably officially moved into the "epic" category of games - if you're interested in knowing more (or are in need of a refresher), have a read through the C&C Canon. Trust me, you'll probably need it - with around 30 minutes of video content in this expansion, it really does help to know the backstory."
