Harry accidentally revives James and Lily. James/Lily/Sirius
James/Lily/Sirius are in a coma for about a week or month definitely before year 6 starts, they forget his birthday like they don’t care

Only Remus knows that Harry revived James/Lily/Sirius
James or Sirius gives Ron the Marauders Map and maybe his broom, more friendly to the Weasleys/Hermione then Harry
Lily is pregnant with Harry’s sibling, think she was pregnant before she died not sure definitely is during the story
Remus is a father figure for Harry, he knows Harry’s tells, starting to see that James/Lily/Sirius and Dumbledore are assholes
Might have abusive Dursleys
Might be Albus Dumbledore bashing Definitely James/Lily/Sirius bashing
Think Harry is gay or might be in relationship with a Slytherin not sure
Might be a Master of Death or Necromancer
Harry saves Sirius from falling in the veil, set after the Department of Mysteries
It’s on AO3 but not sure if it’s on FF.net. I might end up editing if I remember more
