When Hayden was found, he was lying amidst chaos, covered in blood, with a gem on his forehead shining brightly, protecting him from suffocating in the surrounding vacuum. The rescue team dragged him away, back to the medical center, where several doctors discovered that the gem on Hayden's head was actually a fragment of a Cosmic Stone!
Clearly, within the Ancient Mage Tower, there would be no way for a fragment of a Cosmic Stone to find its way to someone's head on its own; meaning, there must be an intricate connection between that beam of light and this Cosmic Stone fragment.
The doctors attempted to remove the Cosmic Stone fragment from Hayden's head, but they quickly realized the fragment was filled with flowing blood and had fully fused with Hayden's skull. If they wanted to remove it, they would have to shatter his skull.
Subsequently, the doctors immediately prepared for surgery—they really planned to shatter Hayden's skull.
