The Quantum Abyss is a region of space where dense neutron stars, even larger dark stars and black holes interact in a way that violates the laws of physics, and causes shifts in space time. It's a chaotic, ever-changing environment.
The abyss is filled with large dark stars orbited by dense neutron stars, which causes all nearby celestial bodies to be chaotically pulled into different directions; the concentration of such massive objects creates unusual effects on gravitational waves and the fabric of space-time itself. The area around the abyss is full of warped chunks of organic debris, and the environment is described as chaotic and ever-changing.
There is a path through the abyss of relatively unaffected space-time deemed safe enough to travel, but only with the proper coordinates. Getting too close to gravity wells and their space-time drop-offs is fatal, as living organisms will be stretched into nothingness.
While the abyss is a highly dangerous area that can rip objects and intelligent life into nothingness, there are some creatures present around the abyss that attack any traveling ships. They are white, four-legged creatures whose center is comprised of a single large orange and black eye. They fly through space at ease in flocks. Their legs are pointed and durable, used to damage ships they target. The creatures can seemingly turn into white energy and enter ships through concentrations of other energy.
Another species seen in the abyss are pods of titanic abyss whales: easily the size of a small planetoid, they feature bright blue eyes, tentacles on their pectorals and tails, rock-like armor that bellows out its own atmosphere, and an entire ecosystem of sustained life in a forest growing on their backs. The creatures even experience their own precipitation. These creatures naturally know how to traverse the abyss while avoiding space-time drop-offs.
The abyss whales have parasitic creatures living in its forest, including large insectoids. While hitching a ride on an abyss whale, Keith and Krolia witness a blue light crash into its body like a comet and discover a black, white, and blue canine creature left in its wake. The canine creature is capable of teleporting short distances in bursts of blue light.
- Keith and Krolia experience two years' worth of time traversing the abyss, while time flows normally for the rest of Team Voltron.
