"Sagittariuses, elusive and filled with expansive knowledge and speed, are a Fire Sign. They have a natural ability to not only adapt to their surroundings, but to easily move rapidly to new horizons. Sagittarius, of all the signs, is hardest to hold down. This is what links them to the mysterious and mystical Shadows of Westeros. As a magical creature believed to be created by the Lord of Light, worshippers of R'hllor employ both witchcraft and blood to create them. Gifted with intangibility, speed, and deadly weaponry, Shadows undertake dangerous missions on their masters' behalves. Like Sagittariuses of Earth, they're always ready for an adventure, even if the stakes are high."
