As the skies tear asunder, dimensional rifts appear throughout the land. They flood the world with powerful miasma, turn wildlife into demonic aberrations, and threaten mankind. Only the fabled Demon Annihilators, righteous warriors chosen by the gods, can harness enough power to fend off hordes of demons and obliterate the core of the rifts to cleanse the land.

Agnis Flarebyte, the most powerful of a long line of Annihilators, loses her power at the hands of a greedy, corrupt Prime Minister of the kingdom. He vows to keep her magic energy hostage until she meets his demands, thus endangering the integrity of the nation as the looming threat of the rifts continues to grow. Agnis must find a way to regain her lost power with the help of her assistant's magic-gathering strategies, then finally end the rift's menace and the Prime Minister's ploy.
