Elena actually had no idea about these sealed beings and their existence made her very interested. It looked like this topic was something that only the supreme powerhouses of this world were aware of and that was also the reason why Draegor had not told Elena about this matter, as technically Elena was still not a supreme rank powerhouse.
Elena did not blame Draegor for this. Obviously he needed to follow the guidelines of the organisation that he was a part of. And now that she was finally aware of this, it was better late than never.
Then as Alexandriana told her about the derivative concept that this being was capable of using and how the derivative concepts were actually equivalent in status to the other main concepts, Elena finally understood why Azusa had warned her about the derivative concept of the sword that she had ended up creating.
