Where to build a Galactic Crucible

The game's own requirement line, then the conditions of the first stage (possible) and of the planet or star it goes around (placement_rules).

The planet or star
  • Cannot build around Protostars.
  • Must build around a star.
  • Cannot build on planets that have unresearched anomalies discovered by us or any other Empire.
The system and the empire
  • When from (Not: Nomadic empire)
    • The system has a starbase
    • Cannot build outside Empire borders.
  • Otherwise
    • Requires the system is on a Wayline with a Wayport or Wayhold.
  • When Not: any starbase in system (Is waystation starbase; owner? (Is the same as: the scope that called it))
    • Cannot build in systems that have not been surveyed.
  • Cannot construct in the same system as an existing Arc Furnace
  • Cannot construct in the same system as an ongoing Arc Furnace construction
  • Cannot build around Black Holes, Neutron Stars or Pulsars.
  • Cannot build this in Binary or Trinary systems.
  • Cannot build due to existing Megastructure.
  • Cannot build in systems with existing colonies
  • Cannot destroy one of our Consecrated Worlds.

Galactic Crucible stages

Cost lines with a condition apply only to the empires it names (bio-ship empires pay food instead of part of the alloys).

How it's counted

Totals in the head count only the costs every empire pays: 40,500 Crystallized Entropy, 2,500 Alloys.

Stage 1

Galactic Crucible Frame

The foundational framework of a Galactic Crucible, built to support and guide the rest of the station's construction.

Other versions of the Galactic Crucible

Ruins the galaxy can start with or a war leaves behind (restoring one is its own chain of stages) and upgrades that branch off the main line.

Ruined Galactic Crucible (ruined)

Stage 1

Ruined Galactic Crucible

A ruined shipyard, once forged to serve the fiery ambitions of a fallen empire.

Stage 1

Galactic Crucible Institute

The Galactic Crucible has been irreversibly re-engineered to prevent dangerously high energy output. It will remain a stable and secure source of prosperity for the empire.
