Terrene is a universe where monsters, and creatures of all kinds live side by side. Their cultures and societies work in a very similar way to ours, but there's a lot more variables and accommodations for different races because y'know... monsters/creatures. There's were-animals, vampires, goblins, elementals, you name it! Heaven and Hell exist here too. 

• There's no outright magic on the being world (For example, there's no naturally born witches or fairies. But sirens can still lure people in naturally with song if they're trained well enough). The only cold hard magic that exists is in Heaven and Hell.
• There's no major extension or diminishment of life expectancy between any races.
• Being-made being-level-intelligent creatures such as living dolls, robots, zombies, and any other Frankensteinian-like monsters, are made by MAD (man-made animation designer) scientists.

Notes: I took a bunch of inspiration from media like BoJack Horseman, All Saints Street, Zootopia, Monster High, DnD, and probably a bunch more. I've always loved the design opportunities that arise from these types of worlds. :D
