Demons are the lowest form of being and fail ALL THE TIME. Mostly because of a guy with a shotgun and a chainsaw. They also have such a poor relation to the TOTCI that their TOTCI values are negative.
Imps are just some type of demons. The most known type (well at least in my thing) are the ones from the Doom series.
There a lot of species of imps with most of them being worthless cannon fodder.
Hugely related to the hell nobles, related in a way to pinkies, slightly related to flying spherical demons, and kinda related to brain spiders.
They have anywhere between TOTCI -5 and TOTCI -1.
More info coming later.
- This is based A LOT on the Doom saga of video games.
