The man known as “Umberto Calzione” is an former Vatican investigator and current member of the outlawed Order of the Sword of St. Jerome. Having a personal obsession with the Brothers of the Yellow Sign he found himself on the same trail as the other investigators and eventually encountered them on the Viceroy of India.

None - at least none that he will speak of.

The eradication of supernatural evil in the name of Jesus Christ.

None - He talks little of his life outside of his devotions and the current task at hand.

Trapped and isolated by The King in Yellow, feeling his ability to resist the being's insidious attacks ebbing away despite his unshakable faith and unwilling to endanger the world by his acquiescence, Umberto took his own life.

His true identity, his past - almost everything, in fact.
