It works as a means of communication with other worlds including Kandrakar. The Guardians also use it to see things live at an unlimited distance, and as a direct entrance to any destination. The control of the portal is by thoughts which must be well controlled to avoid unwanted effects or results.
A similar portal appeared in the TV series.[when?]
It was removed when Kandrakar was sealed off from the rest of the infinite worlds in Arc 7: New Power.
