You find a hole cut cleanly through the vault wall. No alarms tripped, no witnesses, no fingerprints — pure stealth. Whoever sliced through that hole did it so quietly the guards on the other side never even stirred from their chairs.
Additional thoughts
Visualize a perfect circular hole cut through thick steel — so precise and silent it could only be the work of a master thief. The hole is the entry point, the cut is the method, stealth is the flawless execution.
