Alistair Cohen was supposed to be Athanasia's slave. His days were numbered, and he literally died, but Ophelia gave him another day to live so he could choose.
Alistair wanted to live a normal life without fear of dying, so he signed a contract with Athanasia. But he didn't expect that being bound by a demon was not easy.
"But they both didn't know that their meeting had already been written in the Book of Malum and Fatum. Phoebus wrote Athanasia's doom in his sleep. Then he gave it to the Demon God Orcus in his dream. He never wrote it in the Book of Malum. When Orcus saw what was written, he hid it somewhere in Tartarus." Shelly played the water with her hands while the others listened to her.
"Asmodeus and Lilith never saw their daughter's doom. But I heard from Phoebus that Athanasia was mistakenly prophesied as the bringer of death and destruction. And Alistair was the one who could right that mistake." Shelly continued.
