The Land from the Chronicles of Thomas Covenant.
Most people will dismiss it as being a Tolkien-esque immitation (The Ravers as Ringwraiths, the BBEG is very Sauron-like), this is more a fact that there WASN'T much other fantasy writing out there to draw inspiration from.
The real deal is that there are so many amazing and unique fantasy races, the Bloodguard, how giant culture worked, the vile and ur-vile cultures.
Magic also felt like a part of the landscape, and had an essence of good or evil that could affect the very land itself.
The main character is super annoying, full of self-loathing and a sense of powerlessness for most of the series so to me it was more 'putting up with Thomas's self indulgent whiny uselessness until he observes the next cool scene.
But the cool scenes are so amazing that I can forgive just how terrible he is as a protagonist.
