I love the Great Grey Wolf Sif, and have fought alongside her. I have killed her five times across PC and Xbox 360, and the last was the one that mattered. With other Dark Souls bosses, I enjoy Summoning other players to help. But never with Sif. The fight is one that saddens me. It is a duel to be savoured, a consummation devoutly to be wished.
Even the first time, before knowing much at all about Dark Souls, there was something special about Sif (the wolf’s gender is up for debate, incidentally). I reviewed the game back in the day, and so was playing through weeks before the internet had unravelled Lordran’s mysteries. An occasionally panicked email chain of reviewers from several publications swapped hints and tips about Dark Souls – the only time I have ever known this – and one rumour, since debunked but persisting to this day in dark corners of the community, was that you could somehow save Sif.
