Dimensional travel is usually very straightforward and streamlined. Simply target a representation of a fictional world using the "Open New Gateway" feature, and select it. From there, a portal will be generated proportional to your current size. The device also tracks which dimensions you have visited, and allows you to call up a portal to one at any time
Note: Unless otherwise defined, a portal is one-way, and lasts for five minutes before degenerating. Should you need to delete or modify an active portal, use the Entity Editor.
