@pousaylova6 just to put this into perspective, he already knows a pro-theif is going to aim for them and the only way to keep him from stealing them is to axe the theif. They only need 5 cubes to start extracting power from the cubes, so having 1 in some highly secure vault, 1 in some obscure spot, and 1 directly on hand isn't really the way to go. placing them in a spot where an individual would have to be absurd to go to unless they were obviously aiming for the cubes and then targeting said individual without question, while maintaining a defensive primeter actually makes more sense. However, the current security measures of that cave seem EXTREMELY lacking x.O;
