<u>Two types of fantasy/adventure that you will mostly find are the so-called Portal Fantasy and the Open World Fantasy.</u>
<u />
<em>In portal fantasies, you can create a storyline in which your main protagonist of the story goes through some kind of portal to access the brand new world. Such is the case with Narnia, The Magicians, Alice in the Wonderland. You can create multiple universes and the protagonist of the story may be the one to save them all.</em>
<em>Open World Fantasy is more common and it is like LOTR, The Witcher or any type of RPG games that you can find. This genre is somewhat harder to cover because you have to think about every certain detail in the story and develop everything perfectly. Still, in this genre, you are limited with the possibilities because your protagonist would be able to investigate only that fantasy world in which he actually exists.</em>
Think of a hero/heroine of the story with some tragic flaw
Consider his/her goals
Think of a perfect villain with the potential of being seen as intelligent or even likable to the readership in terms of his action
The rest is basically imagination and it depends on your devotion
