Legend
Eberron provides shortcuts for a lot of the travel, through airships, the Lightning Rail, and well maintained roads throughout the more civilised lands. So you can still make travel a focus, or you can turn it into no more than a brief cutscene, the equivalent of the Indiana Jones style red-line-crossing-a-map scene.My understanding is that one of D&D's core conceits is resource management, dungeon crawling, wilderness travel, and the adventuring party. Indy is swashbuckling, cinematic, and (basically) a loner.
Are there Nazis? Not obviously, but like a universal evil organization?
And I wouldn't consider Indy a morally gray character. He's trying to keep religious artifacts from Hitler.
And there are several organisations considered unequivocally bad, at different levels of play. The Order of the Emerald Claw, the Cults of the Dragon Below, the Lords of Dust, and more.
