Storage determines how long a colony can continue producing before a resource reaches its individual cap. Evidence
For Astraean colonies, Solvault supplies Vulkron, Aurelite, and Deuterium capacity, while Heliovex supplies Astra capacity. The corresponding Varkon buildings are Skarncache and Voltforge; the Veil buildings are Nyxvault and Gloamwell. Evidence
The captured live-world Heliovex entry reports Astra targets of 2,750 at level 1, 5,000 at level 5, and 100,000 at level 20. These are campaign values, not universal constants; consult the active colony detail before calculating an upgrade. Evidence
Treat capacity as a scheduling tool:
- Upgrade when production would cap before the next scheduled login.
- Move or market surpluses when another colony can use them.
- At objective sites, keep both culture-specific capacity buildings aligned when the objective detail says its next level is gated by the lower capacity level.
