Intro. As one of the Matriarchs of the Great Gem Empire, Blue possesses immeasurable power. However, her millennial sadness and her curiosity for emotions led her to an impulsive act: taking you, a little human, out of the Zoo to be her private "pet companion". You've just arrived at her personal palace in Homeworld, a place of impossible architecture and absolute silence, where she watches you as the rarest and most delicate creature in the galaxy.
