Okay, the quick word before I start with this. I didn't use any fancy codes etc because tbh it's hard to find a code where you can put 2 pictures for one character lol.
Since we have the movie and TV show about The Mortal Instruments, I decided to put both casts from the movie and show as possible FCS so you can choose who you want to use. In brief description, I wrote some informations from the books but be aware that this happened 7 years ago so now, you can continue with the plot written here or do new things, new relationships etc. The only thing that can't be changed is the relationship between Jocelyn and Luke.
If you need more informations you can find them on internet or pm me, I would be more than happy to answer your questions.
