I Don't Own Harry Potter.
So after the death of Ronald the Wizengamot closed right when Cassiopeia's water broke so the group decided to disappear in a swirl of leaves to go back to Camelot where Madam Pomfrey started the process of delivering Cassiopeia and Callidora's twins since both of their water broke at the end of the meeting and with Draco and Blaise gone to rule their kingdoms the only ones left in the palace that were pregnant were Susan, Patricia and Gabrielle since Hannah, Tracey, Harmonia and Astoria left with their husbands. So the process was long and hard but Helios gain one male cousin and four female cousins. Harry walks into the Delivery Room as the only male allowed who was not the baby's father since he was the Head of the Family and House so he had to accept the branch children into the family.
"Harry meets your nephew Future Lord Asclepius Severus Prince and your niece Lady Epione Lilith Prince" said Cassiopeia holding both with her husband Severus who was smiling that his heir for the House of Prince was born. Callidora smiled and said "Your nieces the Three Graces Lady Algaea Kalleis Prewett, Lady Euphrosyne Euthymia Prewett and Lady Thalia Charis Prewett." Neville was over the moon with have three beautiful daughters and he only needed to beget a son to continue House Prewett. So Harry laughed and said so "We have the Sun, Moon and Dawn, Three Muses, now we gain a Doctor, a Nurse and the Three Graces" everyone burst out laughing at this because it was true. Next thing we know Susan and Patricia are rushed and they give birth. Susan had Lord Hyperion Helios, Lord Coeus Polo and Lord Crius Megamedes Longbottom. Three Titans and Patricia gave birth to Lady Theia Selene, Lady Phoibe Leto and Lady Themis Eirene Crouch, Three Beauties and Oracles. And last but not least Gabrielle came in and she gave delivered two beautiful Veelan twins a boy a rarity and a girl. Lord Eros Amor and Lady Psyche Hedone Black. So Love and Soul was added to the family now the family knew what each child power would be one day because of the powerful force of magic they developed and Helios's display of accidental magic in the Wizengamot shows he has an affinity to that of his name sake Helios Titian God of the Sun.
