But you are arguing on a topic specifically called out as fact by the author ... This particular argument RJ was very clear on. If you were debating something that RJ was more vague about I would support your supposition that your opinion (if laid out well) is as valid as anyone's. Unfortunately for your argument here, the author laid it out as part of the historical fact about the world he created.

We can discuss all day long about the reasons Traveling vanished, and there could be a dozen of them, but the fact remains that it did indeed vanish and we have been told outright that no AS from the AoL survived the Breaking. You can't simply choose to ignore what was written by the author simply because you find it implausible.
