It's the Idea Store.
How do you find it?
First, find the center of the city, then walk three blocks West. Dreamers always go WEST searching for new lands to explore.
At the end of the three blocks, turn left and follow the sidewalk until you find a set of stairs going down into a basement store.
"You have arrived at the Idea Store."
The Idea Store is a really cool spot. The shelves are full of plots and plot twists. there are sections dedicated to heroes--both male and female, and there's a special section in the back of the store for villains. This corner is a little dark and scary, so be careful. It is definitely not for everyone.
The store always has a "buy one get one free" sale on character traits. This is an awesome deal. Your characters can never have enough traits, especially weird ones, though common traits are not bad.
And don't forget to check out their extensive selection of back drops and scenery. They even have a few pre-made world kits. All you have to do is just add water and stand back.
But please don't do this in the store. The store clerks really frown at this, especially since they're still cleaning up the zombie apocalypse world that an author wanted to sample before he bought it.
Not a good thing to do in the store. The clerks really get upset about cleaning up the pre-made world aisle.
If only it was that easy to get everything you needed for your book at a place like the Idea Store.
