You still think in the limited concept of outside. But i don't think there is one. It's not a world but a plane. The world is hollow and you can touch the skies. Only traveller was able to a reach the place through unexplored means and forces of Abyss, which take the path through seas between worlds. They could only get there through warp and i am sure Irminsul obscures the address. All headcanon btw. Your turn.
