Upon the Arrival of Dawn [EPUB ebook] 

A darkness grows, threatening the delicate fabric of the Universe. An ominous cloud spreads, bringing an increasing imbalance across the Cosmos. Essences bent on wickedness and ultimate destruction are violently stripping the Energy of Life from innocent terrestrial creatures, bringing Existence to the very brink of collapse. Only one Celestial essence boldly accepts the calling to seek out the source of the encroaching evil and restore Harmony once again to Existence. Azrael, humble servant of Eternity, offspring of Existence, will stop at nothing to protect the Universe, mortal and immortal alike.
