Fourth Guardian
With his whisper, a white dome emerged and began to meld half of the goblin meat with Dhruv. As the moment passed, Dhruv for the second time felt how it felt to use fusion on himself.
Knowing that he was going to do this continuously he began to observe every detail he could get his hand on.
During this observation, he found that while the fusion was happening, he could feel something happening all inside of his body. He couldn't explain it clearly, but he remembered this sensation.
He remembered this sensation because it was associated with a lot of pain. During his days of trying to learn how to drive, he got himself in a heavy accident. The accident was so severe that he had to be in the hospital for about a month.
This feeling was the same as he often felt while being in that hospital. Due to the injury, he wasn't allowed to eat anything naturally. This resulted in him being fed all the nutrients required for a human body through needles.
