NEXUS PRIMORDIAL

You are a cosmic consciousness, forging a universe from before time. Accumulate energy, bend the fundamental laws of physics, and guide reality from the empty Void all the way to Transcendence — then collapse it in a Big Crunch and begin again, more powerful than before.

Tune the laws of reality

Six Universal Constants — Gravity, Vacuum Energy, Planck, Fine Structure, Arrow of Time and Chaos — apply to your entire universe at once. Every setting has cascading positive AND negative effects. There is no single "best" build: the challenge is finding the balance that fits your strategy.

The Observer Effect — no RNG, ever

You can actively observe only ONE of the 7 eras at a time. Unobserved eras enter quantum superposition and release bonuses on a fixed timer — 100% deterministic and guaranteed. No loot-box luck, no bad streaks: every reward is earned, never random.

7 eras to awaken

Void → Matter → Stars → Worlds → Life → Intelligence → Transcendence. Each era produces its own resource, has a unique Trait, and feeds the next through inter-era synergies. Neglect nothing — your earliest eras keep boosting your entire universe to the very end.
