There is no squeeze. I can create a large island in the middle of the ocean, populate it with Ewoks, have some rebel scum and a Jedi land there to take out the force field generator, and then have a giant space battle over that island on a planet which they call the Moon of Endor, and nobody else in the Realms would even be aware of it.
To shoehorn something means to put in someplace which is a very tight fit. That's what you use a shoehorn for. Tight fitting shoes. The Realms is so full of wide open spaces, unknown areas, and lack of lore in even the known areas, that there is no shoehorning that happens in situations like this.
