There was a massive celebration that encompassed an entire Principal World. Billions were laughing and enjoying the festivity, and there were life forms of all races participating. However, the most common were two types, one with wings on their back and the second with a bloodline eye on their foreheads.
The Principal World was Solaris, and this celebration that covered the world was the Solaris Massacre Anniversary. Those people celebrated the day the Supernova Race massacred the Heavenly Race and reclaimed their home.
The Supernova Race originally scheduled the anniversary to happen hundreds of years ago. Nevertheless, the events that occurred above the Styx River, the invasion of the King in Yellow, and the awakening of the Incarnation of Death and Destruction, forced them to postpone it.
