Seamstresses
In the world thare cracks. These cracks normal and without thare would be no dreams. The cracks lead to other worlds. The cracks insier book, game, TV shows and almost everything.
I'll use Harry Potter for exapel, lots of people might have thought about a boy wizerd of a school of migic. But they stoped thinking about it or they forgot about it or could't put it togther right.
Severl differnt story may come form the same world. They take palce in differnt times and plases and probaly have nothering to do with eachother.
Most life know nothing them. Exept what are called seamstresses. They control everything, but they have rules. They can never have a family other then thare sisters seamstresses, they can never help without someong asked first are two. There many others, so if you want thear help you must first start a contrast with one.
