is one of the eight founding members of the SMP and the third member of the SMP who joined on April 24, 2020. He is the squire of the Dream SMP and does not get involved in major conflicts, but shows up to big events on the server and sporadically joins otherwise. Callahan is notably the only member on the SMP who has not revealed his voice, and is often mocked by other players for this fact. He also does not stream at all, and is largely inactive on the server.
