Are you in the mood for some harsh metal? The mood to face the terrors of the underbelly of the metal multiverse?
If so, take the black door to your left. The one that leads to the square with the blood-red columns, where the cold wastes start and the terrifying winds blow. Those that will chill your soul with their unearthly howling. Just before the gods of the underground spew forth their heated breath to roast it to a crisp.
