Not sure why you got downvoted. D&D is a medieval fantasy; I’m not familiar with any campaign set in our world let alone a historically accurate version of our world. And the goth movement of today is an aesthetic that I’m not sure even has a direct link to the Goths that challenged Rome, just like someone going around destroying shit wouldn’t have a direct link to the Vandals or maybe even know that the crime is named after the people who sacked Rome.
