Out of character, Jordan and Bojar are two different names for the same person. In character, we've assumed this person's full name is Jordan Bojar. Given that all other mages are referred to by first names, is "Bojar" not inconsistent?
OOC however they are more than two different names for the same person. E. Jordan Bojar is the person who designed the Avernum 2 title, apparently. So there is good reason to link the names. But you're right, Jordan would be more consistent. We could also use both names. There are only three other characters whose full names we know, I think -- Erika Redmark, Patrick Padraig, Cecile Vidican, and one of those uses both. -- Slarty
