Riddle of Adoption [SOLVED]

This is my first riddle. It's supposed to be more fun than hard. There are two answers, and you must respond with both of them. Above it, its brothers and sisters, its family. It's absent, like an eye without its pupil, and yet it's right in front of me. I am the highest, but it is higher. It is both the brightest and dimmest. What is it, and what am I? Hint: I have nurtured your children. What they fight for is beneath us both. Update: Its been solved. The winner: uknown assasian. The answers: [spoiler]The Traveler and the Tower[/spoiler] Explanation: [spoiler]"Above it, its brothers and sisters, its family." Stars. This riddle assumes that the Traveler is Alpha Lupi. "It's absent, like an eye without a pupil, and yet it's right in front of me." If the traveler is Alpha Lupi, it wouldn't be in its celestial body, its constellation. It's located right in front of the Tower. "I am the highest, but it is higher." I meant this more literally than it was taken. The Tower is the highest building in The Last City, but the Traveler is higher. "It is both the brightest and dimmest." Alpha Lupi is the brightest star in its constellation, but as the Traveler, it doesn't shine at all. The title's meaning: Guardians are referred to as the Traveler's children in the Grimoire. The Tower hosts them. The hint: "I have nurtured your children." The above explanation explains this. "What they fight for is beneath us both." The Last City.[/spoiler]
