It was called a "door," but it had no outline of a door, nor any external features at all. It looked like nothing more than a patch of air.
Angel called it a "door" because it had been there when he entered; according to the Text Panel, he could leave from here as well.
It was rather like a teleportation coordinate.
However, only Angel could use this teleportation coordinate. To Sebas, there was nothing there at all.
It was time to go.
Angel murmured inwardly and headed toward the "door."
But just then, a voice came from behind him.
"Wait."
Angel froze instantly, and his heart skipped a beat. Sebas... had awakened?
No matter how he had observed him before, there had not been the slightest sign of awakening. How had Sebas woken up the moment he tried to leave?
A shadow passed through Angel's eyes as he turned around.
Yet when he looked up, he discovered that Sebas... had not awakened.
The one who had called out to him was a wisp of blue flame, floating right in front of Angel.
Angel remembered that when he had first entered, he had seen this flame beside Sebas. At the time, there had been nothing unusual about it; but now, not only had the flame separated from Sebas, facial features had even grown within it.
"Were you calling me?"
The large eyes within the blue flame flickered. "Yes."
Angel said, "You are...?"
Blue Flame said, "I have no name. If I had to put it that way, I am also Sebas..."
It did not conceal its origins and directly told Angel the answer.
It was a "perception port" Sebas had created using divine charm.
Whenever Sebas entered a state of "scholarly fervor," he would sever all contact with the outside world.
