Here\'s an update, yay! So what I did here was, create a huge cube around the core for protection. It is 4 layers, alternating between ice crystal and hardened hull, so 2 layers of each. Then I realized I can\'t have a central hallway because the cube is in the way, so I made a hallway going around the sides, and for esthetics I made the wall of the hallway touching the cube glass, so It\'s kinda like a big window.
And here\'s the inside of the safety cube.
