Would you consider doing another cedric story but paired with femharry and it being a wtm?
You could bring people in from the afterlife or the past for the viewing, then present people such as, weasleys, siruis and remus, amos, ministry oh and the malfoys, maybe even the dursleys with marge ect, you could do it in femharrys fourth year as soon as the other schools come to hogwarts before the goblet of fire is lit. Or you could just do it as soon as hogwarts students arrive without the two other schools being present. Femharry and cedric become friends in her first year and get together end of her third year. He could also be helping the golden trio with all of there saving hogwarts each year but only with finding out information, he fully becomes involved in third year with shack and siruis ect. Please
