Twilight Imperium: Fourth Edition – Twilight Codex Volume III: Vigil

During setup, choose an unplayed faction from the Mentak, Xxcha, or Argent Flight; take its home system, command tokens, and control markers, plus the matching Keleres hero. That hero unlocks when you have scored 3 objectives (pp. 6–7).

No. Choose two non-faction technologies that are owned by other players (p. 8).

No. When you resolve one of your PRODUCTION abilities, you may resolve one additional PRODUCTION ability in any system, but that additional use does not trigger the ability again (p. 5).

At the start of your turn, you may spend 1 influence to treat all laws as blank until the end of that turn. It does not say to discard or remove them (p. 7).

The Keleres gain the Custodia Vigilia planet card and its legendary planet ability card, and cannot lose those cards. The Custodia Vigilia card also cannot have an X or Y assimilator token placed on it (p. 5).

You are neighbors with every player who has units or controls planets in the Mecatol Rex system or in a system adjacent to it (p. 5).
