The Drizzt Card is bad worldbuilding
If you’ve read much of my writing, you know monocultures bore me.
Take a look at any real civilisation. You’ll have a dominate culture with shared beliefs, but the people in that culture will vary greatly.
You can describe the culture of China, Vanuatu or the Unites States in broad terms, yet so many individuals won’t match that description.
Shift over into scifi/fantasy, though, and all bothans are spies (what?) and all dwarves are hard-drinking, gruff soldiers (“even the gradmas?” “especially the grandmas”).
(Seriously, the bothans in the old Star Wars EU crack me up. What use is there in a race of spies? “Hey, does that bothan work for us? No? Do you think we should arrest her…?”)
Monocultures aren’t interesting, they aren’t realistic and they throttle your world’s potential.
Many folks agree with me here.
So they lazily play what you could call the Drizzt Card.
If you don’t know the name, Drizzt Do’Urden is a drow. In that setting, the drow are united under a cruel, theocratic, xenophobic matriarchy. In other words, “all drow are evil”, but at least this justifies it somewhat.
(You still would have subcultures in a situation like that, but whatever.)
Drizzt is a male drow who’s one of the good guys. I haven’t read any of the books on him, but I get the sense he’s a well-written character.
People like him, in any case.
Doing that isn’t an out, though. If orcs are a monoculture - all savage, warlike and nomadic - then having one orc who’s cultured, peaceful and settled doesn’t make your world nuanced.
Let’s take orcs as a given. Let’s say that, thanks to their culture, their blood or both, they are prone to forming raging hordes of barbarians.
That can be the foundation of a rich, vibrant collection of cultures, with unique individuals within each one.
Or it can be a way for PCs to fight Bad Guys without any guilt or consequence.
Honestly, neither is wrong.
But if you’re bored of nameless, faceless, interchangeable, XP blobs for enemies, give Call of the Gods a read:
