"Let's Provoke All The Big Guilds' Geniuses!"

The Celestial Lake was famous because there was a unique natural phenomenon that would only happen when the full moon was out. 

The whole lake would shimmer like crystal-clear mirrors and countless feather-like light would fill the entire lake. 

This phenomenon was strange, but people believed that the lake was a place where fallen celestials' souls rested. 

The feather-like light was the soul of those brave celestials who fell from the sky kingdom to the lake. 

Because of this, the lake was called a Celestial Lake, and there were many Feather Pavilion at the lake's bank, surrounding the lake. 

Many young people liked to hang out from evening to night time, especially around the full moon. 

But the Winged Guild members always came to this place because it was said that they could get better enlightenment when they're around the lake.
