If you want more grimdark and it has to be fantasy, check out Warhammer horror especially the vampire Genevieve. If you’re okay with grimdark science military science fiction, a good chunk of the Warhammer 40k and Horus Heresy lines will fit your bill.

I feel like Hobb is much lighter. For whatever reason I always think of Tad Williams and the Dragonborn Chair as connected to Hobb. I suspect it’s from the Legends anthology but they were only together in Legends II with a different Hobb trilogy setting and Otherland for Williams. Both are great starting points to find authors that have huge bodies of work that could hook you. They were how I found George RR Martin back in the early aughties.
