Indiana "Indy" Graham was a Seraphim citizen and resistance fighter.
Together with his sister, Mackenzie, he worked to undermine the OFS-controlled government around 1922 PD. During that time, they made contact with Mesan Alignment agent Damien Harahap, who falsely promised them the help of the Star Empire of Manticore. (SI4)
Once Harahap was exposed, Indiana accompanied him to Manticore and later Mesa aboard HMS Tristram. While on Manticore, he began a romantic relationship with Lieutenant Abigail Hearns. (HH14)
In 1923 PD, Graham and Harahap, now in the service of Manticore, joined Anton Zilwicki, Victor Cachat, and others in the search for the Mesan Alignment. (CS4)
