Had a big brain moment. Lore dump time.
Demons and angels exist in my fictional world but function differently than they do theologically. They aren't separated into "evil" and "good." Angels can be counterproductive and aggressive, and demons can provide comfort and support. In this way, they embody more the mythological concepts of angelos (messengers) and daemons (spirits). Both are products of technology. Without going into great detail, demons appear in physical space as dark clouds of nanotech that require a host, while angels normally appear via technological devices in the form of AI (angelic intelligence) with the uncanny valley quality one would expect. Angels' physical forms, generally, range from deeply discomforting to infohazard-levels of terrifying.
