The latest Hero's Guide explores the Redhorn Lodes. I myself have just recently visited this place but I already like it. For one, it varies up the color scheme a bit to more reddish tones. I guess that's where it gets its name. And secondly, I don't seem to be wading neck deep in Orcs like I do in Zem-Melek, just to the "north" (not sure about directions in Moria). Once again, minor spoiler warning for those who have not been exploring yourself.
