The First Wave

We have received word that several outlying systems along the galactic rim are being overrun by some sort of invasion force. This appears to have been the source of the subspace echoes we detected approaching our galaxy. What we are encountering now is only the vanguard - the main body of contacts has yet to arrive. Reports have so far been confused, but the "ships" used by the invaders appear organic in nature and do not respond to hails. Our entire galaxy may be facing an invasion of unprecedented scope.

The command below will trigger the "The First Wave" event in Stellaris:

When this event fires, you can choose between these 10 options:

Stellaris events fire in chains — one event leads to the next. Here is how The First Wave (crisis.18) connects.
