Hi there! I am a newbie writer myself and I write about fantasy (the kind that shifts from medieval to becoming a pseudo medieval plot in my novel).
I read and saw your book and it looks promising. Why? For me, you are already sure that your novel Void Requiem is your first passion project as a writer. You love the scifi-fantasy genres so you incorporated that into your own story which was very evident especially that in the beginning you started off with a fight scene happening in your novel's genesis. It may be a brief one since entertaining fights have to be described with your five senses (sight, smell, touch, hearing, and taste like "as I slashed his chest, his blood splattered across my face with my tongue tasting its disgusting saltiness before I could wipe it cleanly from my mouth").
You're also clear that from your own blurb, you intend to have a strong male lead as the MC of your story. But its also important that you do world-building first before you begin writing your story.
Sure. World-building does prevent a writer from writing one's own story immediately because world-building demands a lot from writers like geography and maps, ethnicities and species, magics and artifacts, and all those things that will force the reader into your story but it doesn't have to go straight to that devastating point. You only have two episodes which was why I am saying this in the hopes of you not making my mistake.
When you begin world-building, ask yourself "Is Void Requiem plot-driven or character-driven?"
Do you want us readers to get to know your novel through the plot/script that you established already or do you want us readers to get to know your novel through your MC(s)?
From what I've read in your two episodes combined with the blurb, you should be making your story character-driven. I am not forcing you or anything but this is based on I've noticed.
Of the three tags you've posted, this tag #space_adventure should help you answer that question. Who's space adventure are we talking about? Knowing who's adventure it is, it means we should see Void Requiem's world through this MC(s).
When you world-build, make a world that will shape/force the MC to become the universe's next overlord. A world is built to matter, affect, and transform your character(s). So far, you've got one and there are no other POVs. Harry Potter is character-driven because it focused on his childhood and how he entered the wizard world. He is also a good example of how the world-building is seen through him as the main character. This path is more immersive than plot-driven because we relate to the human/MC character rather than that plot (which isn't human but simply made of paper, word doc, scrivener page, or rotten data).
If you decided to make Void Requiem more plot-driven where everything is set and you just need your actors to do their part, then its your choice for introducing your world to us in that way.
I'll stop from here and feel free to tell me if I'm wrong or not but I really want to know how Void Requiem will turn the MC into the overlord of the universe.
Thanks for this thread!
