You can create a permanent pair of portals that bridges the gap between two points in space. The more accurate your knowledge of a location is, the quicker it is to make portals that connect to it, with locations you can directly perceive being instant. Your portals may be in any form you desire, but each may have up to a maximum surface area of 10m^2. There is a slight gap in the bridge between the portals that may cause a slight delay, due to the need for them to perfectly sync with each other. Your portals must be created in empty space, though anything can go through it and it is a two-way connection. You may have only one pair of portals active at a time, but may destroy them at will.
