Ariel – Ariel is a curious, determined, and arrogant man. An unparalleled genius and an accomplished scientist and philosopher, he has become disappointed with the inability of these disciplines to answer his deepest questions and seeks to uncover the universal truth that they have failed to provide. He strongly believes that discovering such transcendent knowledge is the only thing that can make his life worthwhile. He is based on the character Heinrich Faust from Goethe's Faust.
Helena – Helena grew up with Ariel, and loves him deeply. She is the only person that Ariel has ever truly loved. She represents innocence and all that is pure and good. She is based on Gretchen from Goethe's Faust.
Mephisto – Mephisto is a rebellious angel who was cast out of Heaven. He desperately yearns to reenter Heaven and be reunited with God. He deeply disdains humans, whom he considers inferior beings unworthy of God's love. Mephisto is one of the only characters to retain his name from the original Faust story.
Plot
The story takes place at an unknown time and place on Earth. God has commanded all angels to serve alongside humans on the Earth, but one angel named Mephisto has refused to obey this order, claiming that he takes orders from God alone. For this, Mephisto is expelled from heaven. God eventually decides to give Mephisto one chance: If Mephisto can claim the soul of God's favorite man, an alchemist and scholar named Ariel, then can he return to heaven. If not, then Mephisto will be condemned to hell forever. Mephisto agrees and searches for Ariel. Meanwhile, Ariel is introduced, and he begins to ponder his research on the true meaning of life and why God created humans. He concludes that neither science nor religion can truly answer these questions. Feeling restless, he decides to leave his home country to search for answers. He bids his farewell to everyone, including his lover Helena, as he departs on a quest for answers, vowing never to return. Years pass as Ariel searches. He becomes addicted to drugs, and eventually turns to the occult, during which he sees a brief vision of Mephisto. He begins to think of Helena, whom he misses greatly, while aimlessly walking through the wilderness, regretting his decision to leave. He gives up his search and decides to commit suicide, believing that he will never find the answers he is looking for. But before Ariel has the chance, Mephisto arrives and proposes a deal: Mephisto will help Ariel in his search for the questions, and fulfill all his worldly desires; in return, Mephisto will claim Ariel's soul when he dies. Ariel is then mysteriously transported to Mephisto's castle, where the fallen angel throws a feast in his honor. At the feast, Ariel agrees to Mephisto's contract, but with one modification: Mephisto can only claim Ariel's soul if Ariel experiences joy so sublime that he wishes to live forever in that moment. Mephisto begrudgingly accepts this deal. After leaving Mephisto's castle, Ariel is found by Helena, who has been searching for him over the years since he left. Ariel is shocked and overjoyed. Ariel and Helena sleep together, and a child is conceived, unbeknownst to both of them. After spending some time with Helena, Ariel decides to leave and continue his search for the truth. With the newfound power that Mephisto has provided him, he feels that the answers are within his grasp. Ariel tells Helena of his intent to go, saying that, while he loves her, "love means nothing to me, if there is a higher place to be." After Ariel leaves, Helena is heartbroken and, vowing that she will continue to love Ariel even in death, drowns herself in a river, also unknowingly killing her unborn child. Both are brought to heaven at the plea of the river spirit. Helena's body is then discovered, and a town crier announces her suicide. After learning of Helena's suicide and pregnancy, Ariel becomes increasingly upset and weeps at the river where Helena died. Consumed with grief, Ariel questions whether he should continue his quest. He blames both God and himself for Helena's death, but Mephisto encourages Ariel to continue his journey, claiming that human emotion will ultimately be their demise, calling it a curse. In Ariel's weakened state, Mephisto's influence over him grows, and he agrees to continue his quest. Helena watches him from heaven. Ariel's story continues in The Black Halo.
