oboy, do I. These are not in any order.
Brandon Sanderson's work is great.
Estes241 introduced the series "The Stormlight Archive", and it's real great with lore and magic. It's not a complicated series at all, just lengthy. If you're into a magical world, with indepth characters, this is the one I'd recommend. It reminds me of HW with its different landscapes and cultures. Sanderson also has basic rules on writing a magic system, which influenced me a little when I was taking care of lore at the time. (Give and take, etc).
The Mistborn Series - This totally inspired the Ashstorms I vaguely mentioned in an event once, and the 'Mistwalker badges' I introduced for the Forlorn event. Also by Sanderson.
I read Patrick Rothfuss's tale with Winds of Winter and the Wise Man's Fear, next. It gets odd in the latter half of the 2nd book, and no sign of a 3rd one, but the first was nice and unintentionally inspired the time I made series of giant spider events. It has nothing to do with giant spiders for more than a chapter, though. Medieval exploration themed.
The Broken Earth Series - I recommended this a few times.. I think. A magical group of people are enslaved in this dying earth and the series mainly revolves around two women. It's real dark and raw. Some parts were uncomfortable because it gets deep in the topic of abuse, but I overall enjoyed the story. It reminded me of Formistry- as the magic highlighted was moving the earth. And the two women involved reminded me of some roleplay I had. It was more acceptable for me to see some conflict from a different way. It has some scifi-medieval theme to it, and dying earth is a technical HW theme
Andrzej Sapkowski - The Witcher Series.. More recent on my list. Influenced my one-shot series 'monster of the month'. Never played the games, though, and the books are different than it, as far as I know. The short stories were nice and quick to read. You start off with the short series, too, not the main series.
The Lies of Locke Lamora - I didn't actually like this one until towards the end. I had to drag myself into reading the first book in the series. It's all theif/pirate related, which may interest you
Tideborne and apparently brit liked the series. So there's that.
I've read a few more somewhat related, but not fully related to HW. List is still being worked through.
