It was the strangest feeling.
For lack of a better word, Tristan felt like he was plucked away from nothingness, turned into a point of light in an otherwise desolate void. Deep in his core, something was thrumming, he then started to sense his surroundings, just like the feeling when he used his Katra.
From what he could feel, he knew that he had returned to the center of Forlorn City, right in the middle of the crowds. He could sense his surroundings better than before. His range has improved, and his sensitivity has also been heightened.
He quickly realized that this happened due to his Katra improvement. After all, since the destruction of his body and absorbing the fragment of the blood elf's memory, he has advanced into stage four Katra.
A feeling similar to being cocooned was crawling all over his body. His mangled body, slowly but surely, is being reconstructed.
