Can be from the world you've crafted, the characters you've perfected and so on.
For me, in my totally original never done before isekai I have to say I just like the world that I've produced and the way that I've gone about showcasing it from the protagonist's eyes, there's still a lot that I haven't revealed from your big bad countries to secret societies and so on, but I will soon enough once
So, what's your favorite thing?
I think that because of ASoIaF and a couple of other character-centric and first person books that I've read, but other than how I write the more inner thoughts of my characters with a bold or just how I write my dialogues. I like that my story is wholly on the characters and hits the right middle spot of being dry and sweet, crude and refined, cynical and optimistic, and much more.
They've gone from flat, basic stereotypes that I threw into a love pentangle for a laugh when I was fifteen, to actual characters with hopes, dreams and fears. The story isn't even all that romcomish anymore; more of a casual adventure with a cast of - I hope - interesting and strange people.
(Also, that it makes watching The Flash CW way more enjoyable because it doesn’t matter if they being clever or dumbly inconsistent, it’s always good for inspiration of some kind. ^^ )
Right from the beginning of my novel I make it clear that the world of Gaia is changing. New inventions are ushering in new ways of viewing the world. Weapons have changed and the way people think about the society is changing.
I have actually been writing a novel based in the same world I created for The Verant Chronicles which takes place 250 years later. The world has out grown the medieval era and has evolved into an industrialized steampunk world and continues to change in that direction. Who's to say that it doesn't continue to evolve into a retro-futurist world? I think a series of books that spanned hundreds or even thousands of years of evolution in that world would be a great series.
