Rules

Basic rules

Each round: 4 phases — Strategy, Action, Status, Agenda
Strategy = pick 1 of 8 cards. Action = tactical/strategic/component actions. Status = score objectives. Agenda = council votes (after Custodian claimed).
Strategy cards determine turn order + special ability
Card #1 goes first; unpicked cards accumulate bonuses.
Tactical action: activate system, move ships, produce units, invade planets
Command tokens spent to act.
Objectives scored during Status phase
Public objectives (staged over rounds) + secret objectives (2 per player).
Political phase votes on Agendas
Each planet gives 1 vote (or trade goods); influence council decisions.
First to 10 VP wins
Usually 6-8 rounds; long game.

Scoring

10 VP wins. Score from public objectives (1-2 VP each) + secret objectives (1 VP) + Custodian bonus + Imperial strategy card + certain objectives.

Action	Points
Stage 1 public objective	1 VP each
Stage 2 public objective	2 VP each
Secret objective	1 VP each (2 held; 1 scored per game normally)
