[...] the Black Lodge is from the mythology of his people, describing it as:
The shadow-self of the White Lodge. The legend says that every spirit must pass through there on the way to perfection. There, you will meet your own
shadow self. My people call it 'The Dweller on the Threshold' ...
But it is said, if you confront the Black Lodge with imperfect courage, it will utterly annihilate your soul.
