My name's Lisse, and my current Very Big Project is As Thick as Blood, which is set about twenty years after Harry and company graduate and is mostly populated by OCs. The main characters are four sixteen-year-old Gryffindors known as the Musketeers and consist of Rory Malfoy, Jim Chang-Potter, Brian Weasley and Maureen Wood. The other really important OCs in that story are Anastasia Krum and Claude Avery, whose existance I will always blame on narcissam and 1975.
I have a few other projects in the works, still focused on assorted children of canon characters. One involves Ron and Hermione's daughter, Dean and Seamus's son, and a three-year-old in a fedora, and it's going to get itself written whether I like it or not. The only other stories I actually have written on the moment focus on someone who technically exists (the mysterious Nott in Harry's year), but like other people, I'm not sure exactly what separates an OC from an OCC. Will be posting more thoughts on that later.
Anyway. I'm here, and I'm posting. Aren't you all lucky. :P
