In theory, there is a door to every world, somewhere in the Hall. You have to know about the Hall and then you have to have some luck finding the door, if you start from the planet side. Once you find your way into the Hall, then finding which doors lead to which worlds is a matter of trial and error. Sometimes the error is fatal.
