They're both angular shapes, but a square is a lot less aggressive than a triangle. We also got rid of a lot of the iron and replaced it with wood, because the color of wood is already warm enough, and as a material, it just isn't as threatening as any kind of iron. And to reinforce the idea that the inside is where the soldiers are, we wanted to populate it with a lot of props or devices that they'd be using like catapults, ballistas, or mills or forges; things that they'll be using to prepare for the battle on the outside. When you put all of that together, you get this where you have the same kind of stone as the outside, you don't have as much iron, there's a lot mroe wood, there's devices that they use for battle, and you definitely have a mood that has changed from a hostile battlefield to this uneasy, nervous, calm-before-the-storm kind of vibe to get you ready for what's happening on the outside.
