Hi! I'm actually planning to write a Potterlock fanfic because yes, there's sadly few of them. However it's Post Potter Era though I'll try my best to put any mention of the Marauders in the story. But as of now there's no guarantee I can finish the story but I'm really excited writing it. I'll post the link here if ever I'm done with it. :D
