I’ve just read the first book from _The Chronicles of Amber_. I’m wondering, why didn’t Corwin or his brother Random take a machine gun, or just a gun, maybe some grenades, maybe some other weapons like a bazooka, then go to the Pattern which is located in the underwater city (they could carry their guns in waterproof boxes), and then appear in Amber and execute Eric?

Or let’s say, why didn’t they take some vehicles from shadow Earth, like a small army of tanks and maybe planes and jets?

Instead of this, they took from Shadow Earth just two pistols and a very little amount of ammunition, which soon they run out of. And Corwin had to fight with Eric using his blade. If he had had a gun, he could have simply killed him.

And then Eric and his other brother gathered an army around 250,000 savages to storm Amber. So a couple of jets and tanks would have been much better than this.
