Cosmic Entities: Neutral cosmic entities.
...however, "good" and "evil" are often seen as worthless conceptualizations by those who stand astride whole galaxies. Here are three cosmic entities that don't care a single whit about "good" and "evil":
The Bringer of Fire: The goddess of fire.
PLX/3340pp. The imperiex of the Green Star universe, as well as the greatest pyrokinetic in the Green Star universe. The Bringer of Fire is fire; at her command, stars ignite or die; galaxies spin off their axies, and gamma ray bursters scourge whole sectors of life. She is also a powerful telepath and potent telekinetic, but the fire is, and always will be, her greatest talent.
The Bringer of Fire is an ascended Stonebuilder, but she feels no loyalty to her people or their legacy: no, she is content to indulge, creating or destroying at whim. "Good" and "evil" are irrelevancies to she who can forge or break asunder galaxies.
The Bringer of Fire watches events on Earth from her "throne" on the sun's surface. Serving her are humans-turned-thoughtforms known as the luminscent sages.
The Mediating Voice-of-Two: The greatest unleashed mind of all.
PL18/510pp. The greatest telepath in the Green Star universe, the Mediating Voice-of-Two is actually a dual being: a non-sentient behemoth without a functioning brain, and a purely psionic thoughtform that permanently "pilots" the above-mentioned ur-beast.
His body obsessed with violence but his mind a thing of peace and tranquility, the Mediating Voice-of-Two continually walks the line between utter hypercarnage and serene inaction. In fact, so divided is he on this matter that these are the ONLY two emotional states he is even capable of!
The Mediating Voice-of-Two carefully observes the drama on Earth by serreptitiously tapping into the Many's Q-lines, from his home in the Andromeda Galaxy.
The Sky Machine: The storm of storms.
PL18/550pp. The greatest robot weather controller in the Green Star universe, the Sky Machine is an Architect superweapon. Fitted with a massive quantity of L-imbued psicrystals, controlled by an AI modeled off the brain of Ancient-Supreme Glorianna Lux, and devout to the cause of the Great Imperium, the Sky Machine is a ruthless destroyer.
Strangely, the Sky Machine has never been deployed during the first two Earthly Purgings, despite the obvious advantages of doing so...
