Many say the light is white. We know really it's green. THe darkness is red. Many attempt to wield the darkness in the crucible, those that succeed will be marked by a red shape. Those that attempt it but don't get it to work are yellow. Clean is green. Yet the red bar gives power. The red bar is smaller, more mobile than the bulky 3 green bars. They allow the user to slip through space as if they have complete control. This is why many enemies have red bars. They keep coming back. It's also why ours are red when near death. The darkness fills us, allowing us to survive better. In this near death state we take less damage. This act is treason if done on purpose. But newer guardians don't have the strong connection with the light they need. The crucible attracts the darkness. It feeds with it. These younger guardians simply can't connect with the light. Luckily we forgive them. But those few who embrace this act, this warping, are invincible in the forever fight of the crucible. But the architects watch over us. As these guardians sometimes disappear and their ghost fragments call out mercy or anger towards our protectors. - Lord Shaxx
