Traveling To The World Of Anime With The Dark Souls System

I've been thinking of creating a novel. I want it to be based upon God Of War, the game, but it's not going to be the greek pantheon that's going to be the enemies here. I will be making my own gods, just like I did with this fanfic.

Around 12 major gods and 24 minor gods. Each major gods have 2 minor gods as their servants. The MC will be a demigod, just like Kratos. I will make a plot that will direct the mc's hatred towards the gods. He will try to slaughter them just like Kratos did to the greek gods.

But first, let's have a talk about our sponsor for today, Raid Shadow Legen- whoops, wrong words there buddy.

Alright, enough about jokes, I will first build the world. Hmm, I will plan it inside my head. I'll let you guys check it after I'm done with it.

PS: Not a fanfic but a novel.
