Bert Brenner is a member of the group MHI. He is a ghost, and is somehow linked to Gracie Worthytown. In 1936, he encountered members of SAVE during an investigation in Rome. He attempted to possess the body of Lodewijk Van Beers, but was unsuccessful.
However, he was able to possess the vessel of the Order of the Blackened Denarius, Naamah during that same encounter. His attempts to utilize her full potential failed however, when Ornias seiezed her coin before it could be surrendered to members of SAVE.
He was the “Ace-in-the-hole” for the group and one of their most powerful members.
