Frontier Doorframe

__NOTOC__
==Description==
Every structure that has ever fallen to an enemy has been breached somewhere. And the breach point, more often than not, is the door.
A door is only as strong as the place where it is anchored and many a would-be warlord has come to grief when their solidly constructed door was torn off at the anchor point.
The difference between a king and a pauper might just be the entrance to his kingdom.
Weapons barely chip it and even explosive powder is not enough to weaken it in a single blow. Siege weapons or divine intervention are really the only way to bring down walls this strong.
