Ruby

Beyond the Obsidian Council, Ruby Red is the highest authority in the clan. Not because she is appointed so, but because they fear her. She is a prized fighter, and no dragon has ever heard her until she was upon them. Ruby is the best assassin in the Shadowbinder's domain, quicker then the lighting she was born of, and swifter then the shadows she now lives in, she can take down anyone she pleases. Information is as easily accessible to her as gold is to a king, she can place a claw on any living or robotic being and read them like a book. You cannot cheat her. You cannot lie to her. And you most certainly can't escape her, because she is Ruby Red, the Crimson Assassin.

Despite Ruby and Xyremita's very different personalities and appearances, they are basically inseparable. They came to this clan together, and they stay together. No matter how many times Xyremita gets wrapped up in her research and talks about things that Ruby doesn't understand, and no matter how many times Ruby is annoying and disruptive, they continue to stick together faithfully.
