The massive expansion Prophecy of Kings for Twilight Imperium 4. The galaxy becomes significantly larger as seven never-before-seen factions are added. Forty new system and hyperspace route tiles introduce new planets and obstacles to the map. Additionally, you can now play Twilight Imperium with up to eight players thanks to player components in two new colors. It's an immense scope, but that's just a fraction of what can be found in this expansion.
