So the video games with a door in the mountain are based on real life and there is a dungeon inside the door full of dwarves and orcs and goblins and gnomes running a conveyor built and other modern mining technology and they will attack you with pick axes and throw dynamite at you if you enter along with a human in knights armor holding a giant sword and human people with machine guns wearing pants but no shirts and if you get far enough there is a portal to another realm?
Also those quads do not look like the quads in the dune video game series, theg are open on the outside and do not protect from bullets
