Marathon Rubicon names the Pfhor home planet as Pfhor Prime. While this is not cannon, does anyone know if the a more correct labeling would have been "Pfhor Primus"; e.g. using the ordinal numbers instead? I suppose a rough translation would be "Pfhor the First" for primus and "Pfhor One" for prime. I don't know enough about latin, or proper use of ordinal numbers, to call it either way.
Sorry if this is the wrong board for this question, but that would be incredibly typical of me anyway.
