I think authors are just realizing there's no real reason to feel limited to a narrow set of genre rules in their writing. There's no reason a mystery novel can't have fantastic elements in it. Similarly, there's no reason why your epic fantasy series can't have elements of a mystery.

The seeds of the past bear fruit in the present.

In my opinion there are two basic questions that any writer tries to answer. "What is?" is the question non-fiction asks. "What if?" is the question fiction asks. That's the question I'm more interested in.

I have an apple that thinks its a pear. And a bun that thinks it’s a cat. And a lettuce that thinks its a lettuce." "It’s a clever lettuce, then." "Hardly," she said with a delicate snort. "Why would anything clever think it’s a lettuce?" "Even if it is a lettuce?" I asked. "Especially then," she said. "Bad enough to be a lettuce. How awful to think you are a lettuce too.

In brief, worldbuilding is different than setting in my opinion. Setting is a room. A backdrop. It's scenery. But without good worldbuilding, you can't have realistic feeling scenery. You can't have cool, unique backdrops for your story.

The truth is that the world is full of dragons, and none of us are as powerful or cool as we’d like to be. And that sucks. But when you’re confronted with that fact, you can either crawl into a hole and quit, or you can get out there, take off your shoes, and Bilbo it up.

For me the really cool parts of being an author don't have anything to do with getting onto a bestseller list.
