A long time ago, a powerful group ruled the lands that would later be known as Equestria. Although almost everyone has forgotten their existence, remnants of their dark legacy still linger. When Discord pretended to be Grogar, his actions brought back a fragment of this ancient group, enabling the return of an ancient evil, known as the "Speaker".

But the "Speaker" knows she cannot bring the shadows of the past alone. She has gathered many powerful allies in the past—those with darkness in their hearts and a thirst for revenge. but all of them have vanished into the mists of time. However, with the help of a certain trio, she believes she can resurrect these allies and restore the strength of the Yellow Eye, all to prepare for the return of the legendary Yellow King.
