TIME’S UP FOR THE GUARDIAN OF THE SPACEWAYS! Across the multiverse, a grim figure has been hunting down Space Ghosts — and his name is Tempus the Time-Master! When the Ghost Planet team arrives to prevent the Council of Doom from escaping during an attempted prison break, our heroes are suddenly confronted by this rogue chrononaut — who quickly proves to be a far greater threat than anything they have faced before. As Jan, Jace, and Blip are scattered helplessly across the timestream, can Space Ghost find a way to counter Tempus’s seemingly unlimited abilities before his own time runs out?
