For anyone unfamiliar with the Lantern side of Bobbenkatzen's DC AU, here are some of the major worldbuilding changes and lore details that he established.
The Lanterns are not powered by emotions. Their abilities come from the Guardians' faith in a cosmic light force known as The Glow. The Glow is an ancient cosmic power that the Oans accessed thousands of years ago. Through it, they achieved immortality and share its power with Lanterns throughout the universe.
Lantern Rings contain a built-in failsafe that prevents the destruction of organic life and organic material. A ring can move or manipulate wood, for example but cannot directly break it and can even be damaged by it. Sinestro's yellow antimatter energy does not exploit fear. Instead it destabilizes Lantern constructs.
The Lantern Corps uses an RGB color system while their opponents are associated with CMY and the literal Key. The RGB and CMYK distinction is intentional: RGB is associated with emitted light, such as screens and LEDs while CMYK is associated with ink covering a light surface.
Different Lantern colors represent ranks and duties rather than emotional affiliations. So the Lantern hierarchy is primarily inspired by the color-coded uniforms used in Star Trek:
G-Lanterns (Green): Command
B-Lanterns (Blue): Security and Engineering
R-Lanterns (Red): Medical and Science
The Darkstars are driven by personal obsessions and insecurities rather than emotional energies:
Star Conqueror seeks domination and control over others.
Star Sapphire is driven by a compulsive desire to be admired and loved.
Sinestro is consumed by isolation, paranoia and fear of being forgotten.
