Lucas was cloned from a warlord who used the gifts of Passion, Sun, and Luck to strike fear in his enemies while neutralizing their attacks and raining misfortune upon them. As his influence grew, so did his overconfidence, and when the First finally came for him, he actually believed he could defeat them. Needless to say, he didn't.
Lucas decided he would help rogue gifted avoid making his predecessor's mistakes. Instead of using his gifts to intimidate his foes, he would attempt to reason with them and convince them to join the Organization peacefully. Of course, that isn't always an option, and Lucas is fully prepared to use his powers offensively if it comes to that.
During one of his training sessions, Lucas suffered an unfortunate accident that severely damaged his eyes. For just a moment, the thought crossed his mind that he might never see again...
Lucas was rushed to the nearest Health-bound Gifted, and his eyes were healed in a matter of seconds. But strangely, his irises had turned a dull gray, and his pupils seemed cloudy and unfocused. A confused and terrified Lucas asked why he still couldn't see, and the onlookers couldn't think of how to answer.
A Gifted's powers respond to his or her beliefs and perspective, but not always in a beneficial way. When Lucas feared that he might be permanently blinded, his Connection made that fear manifest. Now he must rely on that same Connection to see the world as he once did, and only in situations the Organization deems acceptable.
Lucas doesn't blame the Organization for withholding his power of sight. After all, he is as much of a threat as any other Gifted when his Connection is open. It has been two years since the incident, enough time for him to make peace with his condition and adapt to it. His other senses have improved dramatically, and he is skilled at reading people's emotions through their voices alone. But every time he opens his Connection, and looks upon the world with eyes that glow like the sun, he can't help but think about what he has lost.
