Alignment of Exodor

The Alignment of Exodor was an event in which seventeen galaxies were in alignment. It was in a time stasis field, meaning it could only be seen once. The Eleventh Doctor planned to see the Alignment of Exodor, but instead investigated an Cybermen invasion. He did still have some time to go, but choose to clean up and repair Craig's house so Sophie wouldn't be cross with him upon her return. (DW: Closing Time)
