This is the Starcity. In a future where humans build a fake sun to live around because all other suns are burned out.
The Arms of the artificial Sun hold the citys close and the sun itself provides warmth and Light.

The Assembly
 

1. be carefull when removing the supports of the suns arms because they can easily snap off.
2. hold the little city in the bowl in place so the holes match, then push the arm through.
