Lyra was troubled when she was face to face with the person Rex warned her about.
Since he took the time to warn the Supernatural generals leading the army, including herself about Edward, then he must be quite a fearsome individual. Even from observing the person discussed, she could feel the combat prowess radiating from him.
'He's extremely strong, not through raw power, but through intent' Lyra pondered.
In a chilling silence, Edward gazed at Lyra intently.
As he did that—the skin-tight black armor that he wore that seemed to be alive moved and reached the Executor. Edward gave him chaos energy to heal his injuries, and visibly—Lyra could see that the Executor was recovering.
Before Lyra could say anything, four Shapeshifters made a sneak attack.
Melding with the environment, they appeared behind Edward and launched a series of blows.
Each was aimed to impale and instantly kill Edward.
