Empress Andraste looked at the projection of the battle that was happening in real time.
All of the Nations in the Central Continent had spread out their forces to look for traces of the battle between the Prince of Darkness as well as the Holy Order of Light.
However, when the actual location of the Palace of Light was revealed, all of them were taken aback because it was in a place that they didn't expect it to be.
The fortress of the Holy Order of Light was located at the very center of the Central Continent.
The main reason why no one found it was due to the fact that it was hidden inside a Forbidden Domain. Just like the Seventh Sanctum and the lands of Hyperborea, everyone that tried to enter this Domain were all nearly annihilated.
There were still survivors who traveled in the Seventh Sanctum, and one survivor from Hyperborea. But the Forbidden Domain of the Palace of Light prevented anyone who entered it from leaving the place.
