Thrawn's Revenge is a large-scale mod for Empire at War: Forces of Corruption. It includes the events of the Galactic Civil War after Palpatine's death at Endor, up until the signing of the Pellaeon-Gavrisom treaty. If you own the Steam version of EaW, you will have to complete extra steps to run the mod after installation. Please see the manual for these steps.
We're doing a significant overhaul to all of the Galactic Conquest scenarios in 2.2; some completely new ones, some redundant ones removed, some significantly reworked and some formerly single-scenario setups split into multiple scenarios because of how much they cover. Part of the goal in this is to add in more story where it's appropriate, but we'll get to that later once the project is closer to finished.
For now, here's the layout of the Endor Aftermath GC. This GC is the primary Warlord-focused GC in 2.2, with all Imperial groups plus the New Republic, immediately after the Empire's fracturing. We'll have a news post soon where we break it down a bit more.
