Heigao'er was the previous Master of Dreams, who declined at the brink of fiery demise, and perished in the secret chamber of the Starry Kingdom.
When Rod first acquired the realm of dreams, his frenzied soul was attacking the Obelisk.
Later, during an assault on Rod, he was killed by the auto-activated Divine Blade.
At that time, his soul had lost most of its strength, yet when Rod sent it into the first star of the dream realm, the "Dark Devourer," it still enhanced the star to its highest state before quantification.
For some unknown reason, the soul strength granted was too little, far from matching the rank of the "Dark Devourer."
Regardless, Heigao'er is dead, his soul cast into the star.
"Why does it appear on the tombstone at this moment?"
Rod suppressed the terror in his heart, looking at the name above. Normally understood, each scratch is the name of a Master of Dreams.
The current Master of Dreams is at the bottom, with red text marking him as still alive.
