Hang on
- Humans and other “good” species (dwarves, elves, halflings, etc) are usually diurnal- we’re active during the day.
- As such, we associate the light with “goodness”, and thus refer to good things with terminology referencing light, the sun, and so forth.
- Orcs, goblins, trolls, etc follow “dark lords” and “dark religions”, they live in “dark kingdoms” and join “the forces of darkness”.
- They’re also usually nocturnal.
I’m starting to see where the cultural confusion may have come from here.
