So question is: why can't Sunfire get the title for the Loreroot Consul? If I remember correctly Mur said that even long gone characters can receive a title IF they ask for it. Sunfire is here, even if he said he's inactive. I see him more than others.
As for the KC mercenaries, I believe they should receive their titles since they were quite a big part of MD. They started the whole liquid dust, spores, insulators etc stuff which was quite popular back then.
