For Finn and his human allies, who have ended up at the center of this conflict either through circumstance or manipulation, this is an unprecedented opportunity. If they can band together, they may be able to outwit the Celestials and finally earn their fellow humans a place of independence and power in the Crown Dominion. But first they must locate and master ancient artifacts of immense power that could give them a needed edge in the conflict ahead. And all while ducking the forces that are determined to knock them off the board for good.
