There are a few, but I'll share the 2 big ones:
The multi-perspective narrative.
Being an Epic Fantasy set in a different world, there is a lot of magic, history and a LOT of people. I managed to build this universe with a main lead character within each relevant group, and each one of them will cross the others' paths in a way or the other. This creates a massive story where there is not only one good/bad, one hero/antihero, one villain/saviour.
The reasons behind actions.
The Power of Love Trilogy (of which my webserial novel here is the prequel) has the same structure.
Motivations are as important as the events and their consequences. For this reason readers will be able to chose who to root for. Even the main villain in my serial here, The Power of Love: A Tale of Time, can be seen as the hero by many. And I like that!
