Martin Guildbreaker

Martin Guildbreaker is an important Mason and agent of the Alliance polylaw investigative branch, whose investigations into the stolen Black Sakura Seven-Ten list instigate much of the plot of the Terra Ignota series.

As a close confidante of Emperor Cornel MASON, Martin is a Familiaris Regni, an Imperial Nepos, the first member of the Ordo Vitae Dialogorum (the Order of the Life of Debate), and the designated successor to the Masons should J.E.D.D. Mason temporarily refuse the position.

Appearance
Martin is of "vaguely Persian" descent, with brown skin and black hair. He usually wears an impeccable square-breasted Mason's suit, "light marble gray", with the one white sleeve of the Annus Diologorum and the dark armband of a Familiaris Regni.

Personality
Martin is an intensely loyal Mason and servant of both Cornel MASON and J.E.D.D. Mason. He is a skilled investigator, good at keeping control of his emotions, and operates in a serious, by-the-book manner. He is friendly with Mycroft.
