Some facts about Apollo 13 are that it really faced a major crisis in space. There was an oxygen tank explosion which endangered the lives of the astronauts. Fiction might be any made - up stories about secret missions during that flight that have no basis in the real events that were documented.
I'm not sure specifically what the 'hestia story' is without more context. It could be a fictional story, a personal account related to someone named Hestia, or something else entirely.
Let's assume Hestia's story. Hestia was a kind-hearted goddess. She was in charge of the hearth, which was the center of the home in ancient times. One day, a poor family was struggling to keep their home warm during a harsh winter. Hestia noticed their plight. She sent a gentle warm breeze into their home, making the hearth burn brighter without using more wood. The family was amazed and knew that it was a blessing from Hestia. From that day on, they always made offerings to Hestia and told everyone about her kindness. And Hestia continued to watch over all the homes and families, spreading her warmth and love.
The story of Hestia for kids is usually about her being a kind and gentle goddess who takes care of the home and hearth. She brings warmth and comfort to those around her.
Some fanfictions might also take a more creative approach. They could place Apollo in alternate universes, such as a world where the legal system is completely different. In this setting, Apollo Clay has to adapt to new rules and challenges, which makes for an exciting read as we see how his core values as a lawyer are tested in these strange new scenarios.
Hestia's possessiveness can shape the plot in many ways. It might lead to Percy being isolated from other characters who could be important to his development. This in turn can create a series of events where Percy has to either break free or come to terms with Hestia's possessive nature. Also, it could attract the attention of other powerful beings who either oppose or support Hestia's possessiveness, adding more twists to the plot.
Apollo could marry Artemis' handmaiden. Since he often crosses paths with Artemis and her group, he might fall for one of the gentle and nature - loving handmaidens. This would be an interesting choice as it would also create a connection between Apollo and Artemis in a new way.
A mortal poet or singer could be a likely love interest. Apollo is the god of music and poetry, so he might be drawn to someone with a great talent in those areas. Another could be a beautiful nymph. Nymphs are often associated with nature and beauty, which would attract Apollo. Or perhaps a priestess dedicated to his worship. She would already have a spiritual connection to him, which could easily turn into a romantic one.
