What are some dark, grim fantasy books that nobody talks about? No GRRM, no Abercrombie, no “usual suspects.”

I’m on the hunt for fantasy that’s dark, gritty, morally grey, and just a little bit cruel… but I’m tired of hearing the same names over and over. No George R.R. Martin, no Joe Abercrombie, no Mark Lawrence, no Poppy War, no Blacktongue Thief — I’m talking truly underground stuff.

So, hit me with your weird, under-the-radar dark fantasy recommendations — the ones that never make the "Top 10 Grimdark" lists, but you secretly think are masterpieces.

One hidden gem I highly recommend is the Coldfire Trilogy by C.S. Friedman
