UNDERMINING IS NOT THE SOLUTION
From the desk of the Evil Overlord, Lord Bane McSnively
It has come to my attention that some of you have been attempting to mine deep into my fortress, underestimating my defenses.
Let me be clear: undermining is not the solution. In fact, it's not even a solution. It's just digging. And digging is not going to give you access to my treasure trove of world domination.
I have traps, I have minions, I have laser beams. You will not succeed.
So, I implore you: do not attempt to dig beneath my feet. Instead, try the front door. Or, you know, just ask for directions. We have a nice receptionist who's quite friendly.

Or, if you insist on being a rebel, you could try this route.
