Rainbow planet, was a residential planet in the Fal galaxy, where there would be an arch of rainbow after every rainfall in the sky. Sometimes the arch was brightly colorful. Sometimes it was a little pale, with a beautiful translucency which people adored as much as its starkness on occasions. The name of the planet was from this arch of course. The HQ of Prometheus was also located there.
Ye Chong was an action-oriented person. He would not want to waste his youth on Windstar. He planned to leave the planet after discovering the syndrome to be null the whole time. The MPA had some issues with Black Coves back then but Ye Chong had never seen the fireworks in the sky with them flying against each other ever since. Ye Chong would not buy the fact that the forces had forgotten his existence nonetheless.
