Bernard the Butler would like to know who is calling. It would be best if you had a calling card.
A few things you should understand about Bernard. He is the character I play in a Dungeons and Dragons campaign John runs.
He is a 6'7" coal powered, tinman butler. He worked in the home of a merchant until said merchant and his family all mysteriously died. Bernard carries shoe polish, a pocket watch, and he has revolvers and bayonets concealed in his arms. It is a mystery what use a butler would have with such things. Because of a serious case of OCD Bernard still looks shiny and clean as the day he left employment and joined the party.
