From The Heretic Knowledge Vault
This poor lad was a junior priest in the Reformed branch of the Veracian Church, or at least he was when PCs Argus, Sister Rose, etc., encountered him on the road to Nautkia. His role was to guide them to the Reformed temple there, from which all manner of additional merriment would ensue. Sad to say, this "merriment" included him falling off the cliff behind the temple; whether through accident, of his own volition, or with ... help ... is never conclusively established, but the smart money is definitely on the third of those possibilities.
Prior to his sad demise, Kelso had indicated that he knew something about the mysterious Father Egbert, who would leap to his own doom (sort of...) from that same cliff only hours later. It doesn't take a wild leap (so to speak) of imagination to conclude that there's some connection between these two events, but just in case, there have been indications that the late brother's job description included that of "snitch." Needless to say, in a community that runs on smuggling the way Nautkia does, this is not one of those things that predisposes one to a long, peaceful life. In any event, he's gone now, leaving a fiancee (the rough-and-tumble Lisebeth Rogeriel) who's not as heartbrokenly bereaved as one might expect.
