Under a star and an oak tree (слэш)

Few Omegas clearly remembered the exact moment their pups were conceived, not because the fever of heat clouded their minds, as the Maesters said, but for something far more powerful: only a sincere and pure union could be remembered. Maekar recalls with astonishing clarity the instant Egg was created in his womb, not in the cold bed of a political marriage, but beneath a shooting star and an ancient oak tree, in the arms of his brother, Baelor Targaryen.
That is why, upon seeing Ser Duncan's painted shield, Maekar didn't hesitate to give him the last memento he had left of his beloved Alpha.
