Leonardo was once a celebrated adventurer of Tolria, but his fate took a dark turn after a perilous encounter with a great Wyrm. He descended into madness, turning to gruesome experiments on himself to achieve immortality. His body became a twisted amalgamation of flesh and metal, and he began carving a path of destruction across the Underhollow. Eventually, he found his way to the continent of Osira and founded The Ebony Tower, a dark and foreboding structure that dominated the Burned Woods. With his mastery of flesh and machine, Leonardo conducted vile surgeries in attempts to create monstrous abominations in his own image. His twisted obsession was only stopped when a brave group of adventurers, The Sunsations, defeated him by destroying his tower after cutting down the flesh tree which grew within it. Leonardo's story serves as a cautionary tale of the dangers of unchecked ambition and the cost of seeking immortality through unnatural means.
