The Sentinels are left with two planets to complete their original mission to rid the quadrant of war: Peryton, a cursed planet, and the Invid homeworld Optera. This is an exciting epic finale as all of the various characters in the power struggle converge - The Sentinels, The Invid Regent, the evolved Invid scientist Tesla, the REF, the remaining Zentraedi and the renegade Edwards - on a drastic fight of domination surrounding Optera.

This volume completes The Sentinels campaign that took many familiar characters from the Macross Saga across the universe to investigate the Fourth Quadrant. This final volume ties all of the loose strings from the saga rather quickly, but in an exciting ending the reader won't see coming. ( )
