This might not help much, but I'm currently working on a fantasy manuscript and my main tool I use is beauty. It is that vague when I use the word, but someone mentioned vivid imagination. So I try to light the world up with beauty as I write, yes, even when I get to the violence and the sad stuff in life.
I've only just started the story and I've got a long ways to go. It'll take many years to write. This is because I am an extremely slow writer since the summer had finished. I used to be much faster, but I'm learning to take my time and delve deep within the scenes. That's what I enjoy doing now, though.
Beauty, that's what drew me to fantasy when I began writing for the first time. The first story I ever finished tried to capture that imagination. I was 20 or 21 years old, just eight or nine years ago and I sat down at my Aunt's computer one day with no knowledge of how to write or have read any novels since I had been a very young teenager, maybe even last reading anything since middle school really, and then I just began writing a fantasy story. I still remember most things about it. Beauty was the key for me to begin writing.
It might be more of an inspiration to use beauty, but I've learned in the recent years that it can be a real thing. But I love romantic stuff too, go figure, huh?
The closest comparison you want? Think Final Fantasy for the playstation, the one with the character Squall. That was the last game I played, other than trying out WoW. But Final Fantasy seems to have that magic touch of beauty. But I'm a little different with my stuff, so take whatever I have to say as inspiration first before anything else. That's what got me started and I still use it to this day. No publishing credits to show for it yet either, so again, I'm just rambling. Thanks. Cool avatar by the way (Anonyouth).
