Those of you who are fans of A Song of Ice and Fire and related fan-fiction have got another treat for you today.
It's entitled "A Legion For Westeros." The gist of it is that the Ninth Legion, thought lost in Britain (although some recent evidence have suggested it wasn't), materializes in Westeros when King Robert Baratheon is on his fatal hunt at the tail end of the first novel, A Game of Thrones. After some initial communication issues, King Robert and his entourage start to get on quite well with the new arrivals.
Much more of the story is posted on my alternate-history message board than has been posted (yet) on fanfiction.net. All I can say is that sorts of interesting changes in King's Landing result from this spanner being thrown into the works at a most crucial time.
And the legionaries haven't even gotten to King's Landing yet. :)
