Forum:Time Lock

How exactly does the time lock function. Now it was assumed in stolen earth/journey's end that a time lock simply prevents you from going back into events that are well time locked. Fair enough, but the end of time confused things a bit. in that story they have to go to such extreme extents to escape the time lock acting as though you can't get out of it too it seals you in and you are trapped forever. How then did the Master and the cult of skaro just fly out of the war they didn't go to any big extremes like that. Winehousefan, 08:15, June 18, 2010 [UTC] &nbsp
