Tempest Spent

Our forces have succeeded in destroying the main facility of the Gray Tempest! With the neutralization of its subspace transmitter, all existing Tempest nanomachines have been rendered inert. Unable to maintain their cohesion, their ships have dissolved into nothingness. Any planets that were covered by the Tempest's "gray goo" are now home to enormous swirling dust storms consisting of nothing but disabled nanites. With time and resources, these worlds could possibly be made habitable once more.

The command below will trigger the "Tempest Spent" event in Stellaris:

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

• Another threat dealt with.
  • Nanite Worlds can now be Terraformed into any standard Planet Class, if basic technological requirements are met.
