Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.The Conjuror's Masque by Tytania Strange
Recommended by Zerbinetta
Synopsis: Mayhem enters the Pot O book as a Christine Daaé is murdered before she can make her debut, a waifish imposter claims her place and Erik seems to be undergoing a strange transformation... and it's up to Carlotta to solve the mystery.
Comments: This fic is wonderful, snarkily funny and filled with wonderful details about the life of an opera singer (Tytania Strange herself is a pro). Her interpretation of how Erik would turn out under these circumstances is also spot-on.
Synopsis: It's 1870, and the Opera Populaire is gone. Those who survived that strange affair are left to struggle with its aftermath while war with Prussia approaches.
Comments: The summary above doesn't even begin to do this story justice. Dark, psychological, moving, and realistic. While researched extensively it never lectures. Everyone is not only in-character, but fleshed out in such a way that makes them feel even more human. Easily the best Phantom of the Opera sequel this troper has ever read. Hasn't updated in a few years though, so be warned.
Synopsis: A small town girl who hopes to one day write operas, Christine's life at the time involves day dreaming of her French teacher M. De Chagny and spending time with her best friend Meg. When she has a chance encounter in the library while looking for a opera book she doesn't know that she's caught the attention of a retired Phantom. Nor does she know that he's quite willing to kill to have her. After all, it's nothing he hasn't done before.
Comments: Very good in keeping in character in a modern setting.
Read with care. This story is freaking creepy—and not in a good way.
Synopsis: A woman appears at the Opera determined to save the theater from the fiery fate she has seen in her dreams. But will her visions leave her at the mercy of the Opera Ghost or will she find an unexpected connection with an injured, masked man she finds deep
Comments: I have to admit it's been a while since I read this fic, but I do remember it being completely and utterly amazing. The OC's perhaps even more fleshed out than the canon characters, and I found myself, a previously hard-core Erik/Christine shipper, preferring this OC ship. The character development and the journey these two characters take is amazing. This is seriously worth a read.
Synopsis: Based primarily on my fascination with The Flying Dutchman the opera and what the suave Erik would make of a certain tragic Scottish organ playing doppelganger...Expect chaos to ensue, of course. POTC and Phantom of the Opera COMPLETE AT LAST!
Pairings: Eh...well, Madame Giry/Davy Jones is the main one, but a lot of other Crossover Pairings hook up over the course of the story.
