Years of the young foals terror now in his teenage years his strength grows, his mental sanity still questioning. The unicorn changed as he has already cut himself and stitched himself as he looks like he crawled out of the grave. His skin grey and pale his body so many stitches as he performed a miraculous surgery, he removed his own heart and his nerve system gone he walks the world with no pain or feeling no mercy or compassion for his test subjects as he calls them. The unicorn thought all life forms were his test subjects to perform on for his sick twisted and mentally psychopathic tests. Celestia and Luna stressed and angry that they are unable to capture this unicorn.
Though one group of five royal guards did find his shelter but only one came back his eyes missing and his muzzle sown shut. The guard scared for life tells what this unicorn did as he set up traps that captured each of the guards, the last thing he remembered was that he heard screaming from the other guards as he saw the room he was in. The room walls were warm and wet as they were skin from ponies of every kind, dragons, and griffins. their bones used to make furniture along with some muscle to make the solid top, their organs hung to make curtains their spines as flutes.
The skulls were used to make bowls and cups, he used all parts from his subject the died and the guard was scared but he was set free as the young unicorn took his eyes and his ability to speak, it took time for the injured guard to return to base, But as soon as Celestia and Luna and an army come to the location of the guards description but the home was found to be on fire all the evidence gone as Luna roars with anger. The unicorn with a grin of placement traveled again throughout Equestria as he found a home of his own in an abandoned town he set up his home in an asylum where he plans to redecorate with the failed subjects he finds.
