This is where Logan is.

Logan is the author of the story and the creator of its assets, he has his own portion in reality that is made of matter, which he manipulates similarly to things described in the stories and inventions, he uses the primitive concept the most often, because it provides the simplest root of construction.

But he isn't a primitive, he lives in a modern city, while being in a magical forest here. This will be where he does his own thing, and makes other stuff, it won't be directed anywhere in particular and be mostly about stuff, which can be modified and improved for the story.

But not all, as he does other stuff while doing the story.
