The Branch Worlds are classified as being read-only, and little is known about the Branch Worlds, other than that a number of them also support the vast machinery required to generate and maintain the two shields. [[Heath]] is able to read information from the systems within such realities which has shown that the inhabitants are currently safe from [[The Crushing Fist]] and its effects, however there is currently no way to project information into these realities.
Since the destruction of [[The First World]], at least one Branch World ([[Amber Five]]) has suffered damage to the shielding that ensured it was read-only. As a result, electromagnetic radiation (radio waves) have begun leaking out, signifying that contact is possible, and transit to the reality within may now also be possible.
