Ed Greenwood, as pictured, wrote almost the entirety of the forgotten realms lore. They are an incredibly accomplished writer, and are responsible for a lot of iconic elements of modern D&D.

Yes, some of his contributions are disturbing and fetishy, but that's a small minority compared to the vast number of things put out. Contrary to what others may be implying here, I feel that avoiding his work out of distaste will leave you much worse off than exploring it with the understanding that some stuff will get freaky, and that you have the ability to leave that at the door when it comes to your own table.

If you're at all a fan of the forgotten realms, I would highly recommend checking out his YouTube channel which contains a treasure trove of creative D&D cannon not published everywhere else.

You have no idea of the quagmire you've wandered into. Chad-zak is a funny meme leave it at that. Don't Google it. Don't delve any further. There are things worse than balrogs down there.
