In addition to being a tiefling lookalike (similar to Auditi), Altria might come to Sincerity for romance advice since she has panquadrant (i.e. normal human romance) feelings for somebody who she admits is probably bad for her but she can't stop loving her... and also maybe annoy Auditi a little bit because a major factor is that Altria is a young ageless immortal and Sav is an old, old, old ancient immortal.
