As I don't know the specific story, it's hard to say the key events. But generally, it could be their first meeting as a key event.
I'm sorry, but without more specific information about who Sophie and Minerva are, I can't tell their full story. They could be characters from a book, movie, or real - life individuals.
Her life was full of significant events. Starting with her education at Hogwarts where she honed her magical abilities. As she became a teacher, she influenced generations of students. When the Dark Lord started to rise again, she was there to oppose him. She was part of the resistance within Hogwarts. She had to make tough decisions during those dangerous times, like when she had to protect students from Death Eaters while still maintaining the integrity of the school.
One key event was her study of law. It equipped her to oppose the dictatorship. Another was her joining the resistance movement against Trujillo.
The first key event was their encounter which was quite accidental. Then, as they spent time together, they realized their feelings for each other. A significant moment was when they had to face the disapproval of Benedict's family because of Sophie's lower social standing. But through it all, their love grew and they finally overcame all the obstacles.
It might be a story where Sophie Parker got lost during a trip or adventure. Her friends or family then launched a search, facing various difficulties and challenges along the way. They could have had to deal with rough terrains or uncooperative witnesses, all while being desperate to find her.
One key moment is when Sophie first enters Howl's castle. It's the start of their connection. Another is when Howl saves Sophie from some danger, which makes her see him in a new light. Also, when Sophie takes care of Howl when he is weak, it deepens their bond.
There were several important moments in Minerva McGonagall's life. Her time as a student at Hogwarts was full of growth. Being sorted into Gryffindor was a significant start, as it led her to form relationships with like - minded individuals. When she started teaching Transfiguration, she was able to pass on her knowledge and skills. During the dark times of Voldemort's rise, she was actively involved in the resistance. She used her position at Hogwarts to protect students and fight against the Death Eaters. For example, she played an important part in the Battle of Hogwarts, using her magic and leadership to defend the school.
One key element is often the exploration of the age - gap relationship. Since Minerva is older, it adds a layer of complexity. Another is the magical backdrop. The fanfic usually takes place in the wizarding world, so spells, potions, and magical creatures are often part of the story.
Key events are the major turning points or crucial moments that drive the plot forward and shape the characters' development.
I'm not certain which exact comic ended Minerva's story precisely. However, generally in Assassin's Creed lore, Minerva was an Isu, an advanced precursor race. Her story often involved interactions with the Assassins and Templars through the Animus - like technology that allowed characters to relive past memories. If the comic that ended her story exists, it might involve a final confrontation between the modern - day descendants of the Assassins and Templars influenced by Minerva's past actions and knowledge.
