In the Cosmic Dawn origin, your species roamed the stars in the early days of the galaxy.

Trapped as the planets cooled, recent volcanic activity freed some of your people. Now it is time to look for other survivors across the stars.

The very star that brought life to your planet has become a threat in the Red Giant origin.

As it expands and overheats the system, your empire can embrace this change or gain strength through adversity.
