Hello my friend. I can definitely help you here. i liked the prologue so I added the series to keep up.
I also got a fantasy comic which involves mutiple character/arcs with over 27 chapters. So if you into those as creator yourself you could check it out:
So a few things to keep in mind:
These types of story are the ones with the most storytelling capabilities. And trust me a good story is everything above all else.
The pace and exposition shouldnt be shoved into peoples face too much, you wanna some nice dramatic events planned ahead for your characters. Treat them like real people, how they would actually react (to immerse readers).
The proper way to add "New words and exposition" is by introducing them in a very cool and exciting way. So while a character is off to journey somewhere, that could be a good time. Or when a character needs to be saved by something, that could a good time to put expose new information about your world. Just avoid too much exposition just by two characters talking to each other. Remember you want the events of your series to be memorable. Have no fear to have very dramatic things happens, then they will remember your exposition and made words.
