Portal 63 was a guardian on a planet in the Delphi Ardu star system that was active over 600,000 years ago during the Age of Bastu as time was marked by the Tkon Empire. He was invested with great powers, including the ability to immobilize starships and could appear in various corporeal forms according to the appearance of the beings he encountered. Portal 63 also had some form of telepathy. He remained inactive until 2364 when the crew of the USS Enterprise-D encountered his outpost along with a Ferengi starship. At that time the Portal learned that the Tkon Empire had fallen shortly after the Age of Makto and that he had been inactive all that time.
