Fics like Hell's Heir and the Tribrid

James Potter, left sterile by a Death Eater’s curse, and Lily turn to desperate measures. In a midnight ritual, they summon Lucifer Morningstar, who—intrigued by their courage—offers a fragment of his angelic essence. From this pact, Harry Potter is conceived, destined to be more than mortal, carrying both magic and celestial fire in his soul.
