Im building a imaginary world and story (help wanted)

[Demonic cupcake]

My dad was giving me book suggestions and the converstion of early sci fi and fantast came up. I had this idea

The year is… irrelevant. The world in split in two. Literally. With a stripe down the middle of “the middle zone” or as sone like to call it (my main male character) “the friend zone” on one side is the land of fantasy. Magic rules here. And on the other side is sci-fi this is the land of tehhnology and the futuristic (very anti magic here) both sides hate each other.

What i need:
Im not a sci fi expert. While how the fantasy world works seemed obvious the second i got this idea the sci fi part is still taking a while. Help me with it? Just spill ideas

I honestly think the more important thing to consider is how and why that split exists. Basic premise justification.

From there, how they balance; if they know about each other, then how they counter each other in technology (through which you get ideas for how they work), or if they don't... why not, I suppose.
