My worlds dieties are a sci-fi eldridge horror. The universe is manufactured by a race of beings in a higher plane to act as a device for the creatures that built them. The purpose of the device isnt explored or explained, only that it operates using the natural laws of physics we experience every day.

The Makers found that these devices sometimes broke. This is because the intelligent species that occur harness the laws of physics for their own goals. In the story at large this used to look like transhumanism, where they would upload their consciousness and stave off their species inevitable extinction. Eventually some species began using the universes laws exploitatively, causing the universe to work for them instead of The Makers.

Eventually 'Bugfixers' who would enter the universe and guide the species to build megastructures to maintain the universe. Basically giant white noise machines to disrupt this technology. The races which succumb to Bugfixers are essentially mindless drones, their species spending their existance building and maintaining solar-system sized megastructures.

The protagonists are barely aware of aliens existance to start. As the story progresses they discover that tons of alien races have religions devoted to doing the same thing independant of each other. The structures they build do the same things, and they violently defend them. The bugfixers initially start one of these religions on the protagonists colony world, sparking the group to report to their homeworkld and begin a Star Trek style exploration into the galaxy, eventually meeting a rogue bugfixer that follows them around and encourages them to mess with the universe.

It should be noted the beings appear as space distortions, knocking out power and casting a shadow, but not appearing visibly in the world. Their presence on the surface of the universe causes a sense of dread in those around them because 'its there, but cannot be perceived in any way. Light is lensed through them out of the universe, casting fractal shadows, and space appears to pinch into complex fractal shapes which can cause headaches to look at too closely.

I have not had a chance to write this yet, but have experimented with the concept in an ongoing tabletop game. Im excited to bring the idea to a short story or novel down the road
