Alignment of Exodor

The Alignment of Exodor was an event in which 17 galaxies were in alignment. It was locked in a time stasis field, meaning it could only be seen once. The Eleventh Doctor planned to see the Alignment of Exodor, but instead found himself investigating a Cybermen invasion with Craig Owens. Despite still having some time after this adventure, the Doctor chose to clean up and repair Craig's house so that Sophie wouldn't be angry with him upon her return. (DW: Closing Time)
