Phased Planet

The … crew apologizes for the abrupt termination of their initial report. During transmission, … experienced a complete dimensional phase shift, its particle fields rotating out of one dimension and into another! The cloud of psionic energy has been lifted, revealing a glittering jewel of a Gaia World. Fascinatingly, the number of superimposed quantum states appears to have been reset as the planet shifted, and is now increasing at the same rate as when the planet was a Shrouded World. … has used the rate of increase of particle superimposition, and the total number of quantum states at the time of transition to extrapolate a three-month cycle for the planet's dimensional shifts. Perhaps we might develop a method to prevent the planet from shifting... but we should secure the system first.

The command below will trigger the "Phased Planet" event in Stellaris:

When this event fires, you can choose between the following option:

• Incredible.
  • Physics: +None to None

Stellaris events fire in chains — one event leads to the next. Here is how Phased Planet (distar.251) connects.
