Dux bellorum, the title in the earliest texts given to Arthur (not king.) It translates more or less as warlord, although more literally, it's actually Warduke. I'm pretty sure Gary Gygax would have known that, if the name Warduke rings any bells. Although the character he created sounds more like the Horned Helmet character of Frank Frazetta fame. See below...
This is a pretty iconic style image. I don't know why that place looks like Orthanc, but those characters don't look like Aragorn and Gandalf and Merry really, at least not to me.
Goblins from 4e. Nice image, actually.
Some kind of Greek warrior. I dunno. Nice picture, though.
The tyrant lizard king in a quieter, more artistic moment. But still showing off his impressive chompers.
I don't know for sure what's going on here, but this is a cool image. Always remember; in my fantasy, magic certainly exists, but it's ALWAYS unnatural and therefore extremely hostile to human life. Yeah, yeah... that's an elf, it looks like. But still. Elfs, if I have them at all, are also uusally unnatural and extremely hostile to human life.
A couple of landscapes from Dromund Kaas, the capital of the Sith Empire in Old Republic.
Castle Ravenloft! What a great, iconic image. It doesn't hurt that Ravenloft is, of course, copying great iconic imagery from Dracula. One of the strengths of D&D was its ability to incorporate classic elements and turn them out as recognizable pastiche. When it tried to be more original is often where it went wrong.
Very early concept art for the "supercommando". As you can probably tell, it ended up evolving into Boba Fett, but there was a whole concept behind him originally that was different, as was the Clone Wars of which he was supposed to (originally) have been a leftover.
Some more intriguing Star Wars concepts.
A fascinating landscape of a fantasy port city.
Some Assassin's Creed Odyssey art, if you go with the female version of the main character, I believe.
A typical day in the gallery forests of the Morrison Formation, with two Diplodocus emerging from the forest into a ferny meadow.
Nedry from Jurassic Park. The little guy is the Dilophosaurus from the movie. The big one is what an actual Dilophosaurus woulf have looked like.
DEUS VULT!
I'm not quite sure what this desert warrior thing is; maybe a hobgoblin or something, but it's a very cool image.
Luis Royo. I once kicked off an entire campaign based around this image. Turned out great, too.
Some kind of spirit of the wild type thing.
Shipyards in deep space.
A pastiche of the famous Death Dealer character created by Frank Frazetta (I told you to see below.) This does seem to be a more proximate visual inspiration for Warduke, even if the title itself seems to come from Arthur.
