Based on the last scene, harper was hurt and defeated but there was a hero named "faramis" who had saved him and healed him from the evil doing's of the demon from the unknown. They gathered a team of hero's while harper was resting, they have called Fanny, Alucard, Miya, Tigreal, and Eudora. Knowing that the unknown creatures from the abyss are not been discovered yet, they have prepared themselves and gather strenght to defeat it.
Hence, The war has begun. Even though they are hurt but they had the heart to prove once and for all, that darkness will never win and no one can stand in there way.
Many people/guardians helped them through the phase of devostation and despair so everybody will still be positive about they're glorious victory
And The Land of Dawn is now safe from evil and grief
