A portal is a frame that allows people or objects to move between two locations. It is commonly used to travel and carry heavy items across a large distance. A single portal can connect to multiple endpoints, but only one can be active at a time.
Any magician build a portal, but expertise is required to ensure that it operates safely. Magicians often contract licensed architects, engineers, and inspectors to design and build the portal. In New Salem, city officials require a portal to be registered before it can be built so that it can be monitored for suspicious activity.
