Twilight Imperium: Fourth Edition – Thunder's Edge
A large expansion that centers the conflict around a single, contested planet and introduces new factions, systems, and event-driven modifiers that alter core rules each session. Players command faction-specific forces, explore and seize new worlds, manage resources and political influence, and react to Galactic Events that change objectives and interactions midgame. An alternate Twilight’s Fall mode lets players construct custom factions from salvage, adopt unique asymmetries and components, and pursue a last-stand style victory condition that plays substantially different from the base game.

Rules questions
Answered from the rulebook by Ludoya's rules assistant.
When can I contribute to the Thunder’s Edge expedition, and can I claim a slice someone else already took?
At the end of your turn, you may pay the cost shown on an unclaimed slice and place one of your control tokens there. Each slice can be claimed only once; the first time you claim a slice, you gain your faction’s breakthrough (p. 8).
What happens when the expedition is complete?
The player who claims the final slice places Thunder’s Edge planet-side in a system without a planet, supernova, or printed wormhole; it cannot go in The Fracture. The player with the most tokens on the expedition places that many infantry there, with the final claimant breaking a tie (p. 8).
Does synergy mean my technology counts as both colors?
No. Synergy lets a technology or technology specialty of one linked color count as the other color for researching technology and scoring technology-related objectives—but it can count as only one color at a time (p. 8).
How do I move into The Fracture—is it adjacent to the systems beside it?
No. Fracture systems are not adjacent to the systems they touch on the board. Instead, a system with an ingress token is adjacent to each Fracture system with an egress token; ingress systems are not adjacent to one another, nor are egress systems (p. 9).
Can I use abilities like Space Cannon or Sustain Damage in an entropic scar?
No. Unit abilities—including Sustain Damage, Space Cannon, Bombardment, and Anti-Fighter Barrage—cannot be used by or against units inside an entropic scar. Text abilities are unaffected (p. 11).
Can a planet with two technology specialties satisfy both prerequisites when I research?
Yes. You can exhaust a planet with two technology specialties to satisfy either one specialty or both simultaneously (p. 11).
