The Renaming Of A Once Dead planet
While The Matrix of Gallifrey was trying to come up for a name for the new planet it was creating from what it learned about all of Earth, history, logistics, language's, etc and all of the knowledge of The Time Lord's and everything about Gallifrey. It spent 400,616 years to come up with a name for the new planet it was almost finished creating. Finally it settled on the name Nolamos. Making the planet exactly like a combination of Earth and Gallifrey.
