Think of a stronghold as a living weapon, not just stone and steel. First, blind the enemy to its true layout with false corridors and decoy entrances—so they waste time chasing ghosts while you move unseen. Second, install a network of pressure‑controlled gates and hidden traps that only your trusted few know how to bypass; the rest will be locked out. Third, keep the interior light‑sparse and the exits double‑locked, so any breach is quickly sealed. And finally, reward loyalty with the easiest access; keep the key in the hands of those who will never betray you. With that, allies feel safe, enemies are frustrated, and your position stays iron‑clad.

You’re right—having a secret exit is a clever touch, but why not make it a double‑layered one? A tunnel that looks like a decoy, but actually leads straight to my command core, lets me slip unseen if things go sideways. That way, my enemies chase nothing while I stay ahead.
