  • Learn about life aboard your starship and the home you left behind.

How to Play

Tell your explorer's story by:

  • Rolling dice, answering prompts, and "painting with scenes" to create your lost home, starship, and planets. 

  • Charting a course through the stars, finding secrets and hidden wonders, and collecting keepsakes to remember your journey to a new home.

  • Using real rocks to represent the distant planets you explore. How is a quartz planet different from a gold planet, or a diamond planet?
