interactive format for create a book or a novel Tout et rien

Hi everyone, I wanted to create an interactive format with each of you to create a story like a book or a novel. Each of you is free to express ideas, create characters, settings, salient moments, the genre, the title, the names of the characters etc. and these ideas must make logical sense to each other. use this format as a "pool" and then I will collect every idea and create another to "write" the book or novel.

the main character: his name is joy and he is a hunter of mythological beasts such as: vampires, werewolves ,demons, mummies, timemen, aliens, fairies, jellyfish, gorgons, elves, zombies, time: our times Lunogo: Central America, Europe, Asia, mountains, cities, woods, lakes, weapons: swords, rifles, pistols, daggers, common weapons, crossbow, bow and arrows, etc. the story begins with joy who has a normal life and who works in a school as a history teacher, and one day in his town there happens to be a dead man in a bar and no one knows how he died and the sheriff says that I know this is a common thing and that the investigations are concluded. but in the following days people of all kinds begin to disappear.
