I attended this last year and this year I am helping out as one of the organisers. It’s basically a gathering, in a room, of fans of various TV shows/films/books/games. Last year, we had people representing Sherlock, Doctor Who, Supernatural, The Avengers and more.

There will be games, music, prizes for the best costume, food, drink and general fun. It will be taking place in Central London on Saturday 9th November 2013 but the venue is yet to be confirmed. I will update here when it has been.
