The Elder, it was an unofficial organization, it was an organization where the retired Emperor Class Heroes gathered. The Elder was formed to keep in check the Hero League, in case the Hero League went astray.
Of course, it was voluntary whether one wanted to join The Elder after they retired. The Elder was the reason why Bai Family's foundation was unshakeable. Each of their generations at least had two members at The Elder.
This generation, the Bai Family had three members in The Elder. However, their Elders could not be contacted for two years. What was making worse, the other families started to get to know about this.
The Bai Family was one of the Star City's founders, they had a long history and inheritance. The other families were drooling over their secret techniques. It was normal if one day the other families were against them to get the secret technique.
