The 2021 novel Shards of Earth by Adrian Tchaikovsky includes a type of creature called the "Architects" which I will summarize in my own words as:

Moon-sized creatures from the alternate dimension that is used for hyperspace travel. They can sense the mental energies from psionic humans, and find this sensation so annoying that they will exterminate entire planets to be rid of it. Due to the difference in scale, these creatures do not realize that humans are sentient, prompting a desperate attempt by psionic humans to connect to the creatures telepathically and make them understand that humans are thinking beings.

The earlier 2019 YA novel

Starsight by Brandon Sanderson

includes a type of creature known as

delvers

which I will summarize in my own words as:

Moon-sized creatures from the alternate dimension that is used for hyperspace travel. They can sense the mental energies from psionic humans, and find this sensation so annoying that they will exterminate entire planets to be rid of it.

Of course the details are different, and Eldritch abominations are nothing new, but the broad strokes are far too similar to write off as mere coincidence. While it's tempting to categorize this as Tchaikovsky liberally borrowing ideas from the 2019 novel, I wonder if in reality they both borrowed the idea from somewhere else.

I have only a casual familiarity with the Warhammer 40k universe, but many elements of Shards of Earth seem obviously derivative of 40k. In both cases, FTL travel over long distances is only possible with psychic navigators who can guide the vessel through an alternate dimension. Tchaikovsky's "Parthenon", an all-female caste of warriors, seems to be inspired by the Adepta Sororitas. There are enough similarities that I suspect that Shards of Earth started off as a attempt at an official 40k novel but was re-worked (Tchaikovsky published an official 40k novel less than a year later).

This got me wondering if the Architects, and thus presumably the similar beings from the 2019 novel, are inspired more directly by something from 40k. I am passingly familiar with the Chaos Gods but am not sure if they are a direct analog. Or perhaps the Architect based on some other franchise I'm not familiar with? Or maybe Tchaikovsky did just liberally borrow from the 2019 novel.
