I've never had a player with this archetype before, and I'm looking for advice on how to integrate the blade into SA's story. My (admittedly silly) first thought was that the blade contains the soul of Ambrose Bierce, whose mysterious disappearance was caused by him making contact with Hastur.
My problem is that I don't want the blade to be too much of a help, or too suspicious for the already paranoid amnestic to trust. I haven't run much eith Intelligent items before, and this one is so central to the character that I want to be sure it is believable. Any advice?
