Galpin
Lord Galpin was a British aristocrat who felt strongly about his family's honour. He apparently knew about Lord Barton's daliances with his sister, whom Barton had no intention to marry, and felt that she had been dishonoured by the pair's sexual relationship.
At a ball held by the Duchess of Pemberton in 1813, Lord Galpin was murdered by a Chuldur in disguise, who took on his form, as a shapeshifter. The Chuldur grew tired of "cosplaying" Galpin, since he was "all noble and serious", and next took on the form of Barton, who was far more scandalous, and thus more fun to "play".

Behind the scenes
Though Lord Galpin himself never appears in the story, the Chuldur Galpin was played by Maxim Ays.
