Hannibal Hindenburg-Weller

Hamilcar Hindenburg-Weller II is the son of the Usonian airship magnate Hamilcar Weller and Countess Theresa von Hindenburg. He served in the First World War in the Allied Intelligence Executive. After the party in Marseille, Hannibal was rapidly promoted into the upper ranks of AIX and the leader of a mission into the Amazon interior.

Hannibal and his team left Europe in the fall of 1920 and he's not seen since.
