R.A. Salvatore's Dark Elf books.
Underratted stuff. I assume being by Forgotten Realms means automatic dismissal and ultimately is as it should be. But these first few books here had some pretty good writing. Very beautifully written. Simplified 2D escapist characters. Plot goes along nicely and it's surprising how far it goes. Great injustice and a hero with special abilities at fighting are what keeps the pages turning. Extreme dystopian setting.

How I love the hero in a dystopian setting.

Eventually the series went to 20+ books and quit being interesting. One keeps on reading for a while hoping it picks back up. But Wulfgar is just a dumbass. Not likable like Drizzt. And the dystopia is gone. The world above ground is non memorable. And ultimately Salvatore isn't allowed to say anything interesting I seriously doubt anyway, writing for Forgotten Realms. Clear good and evil and swords flying around. The dark elf society just happened to resemble the real world in some ways to me. And watching the good man trying to survive in it was very interesting to me.
