The events above were intense, bloody, and brutal, but they were not the most important, the foundation that started it all.
The Phantoms had long ago entered the fortress, there were over a hundred of them in the courtyard, and every now and then the last of the squads would come up, making their way through the waves of monsters.
But... none of them could find the passage to the maze, they didn't even know of its existence.
Why?
The Phantoms that were never in the Fortress of the Lone Serpent were aware of the runes, the three commanders, and the monsters inside, but they didn't know about the maze.
It was simple.
All the information that Katrin & Alan and the other Phantoms/Operators had, came from the records of the Unknown Phantom who first came to the fortress before the Eclipse. He had his reasons for clearing the Red Zone.
Thus, both the military and the Phantoms only had the information Silvana chose to share.
