In S. 1206, Gramheart ran as the candidate for the opposition party in the election for the presidency of the Republic of Calvard against Samuel Rocksmith. He campaigned against the current president's policies on immigration as well as his too soft response to Erebonian expansion. Gramheart won the election and took office early 1207, becoming the 23rd President of the Republic of Calvard. In the aftermath of the Great War, he put pressure on the former president, forcing him to demand astronomical reparations from the Erebonian Empire. Once he took office, he distributed those funds among the populace, gaining him immense support.
After Reverse Babel's appearance and Elysium's threat to destroy Baratie Air Force Base, Gramheart contacts the Crossbellian Goverment, represented by Henry MacDowell, and offers that the Republic Army of Calvard could assist in its destruction, an action which would likely result in Crossbell's renewed occupation. He additionally threatens that should Reverse Babel not be dealt with in time, he will have no choice but to deploy the army to defend its national interests.
At some point after the second Crossbell incident, with the help of MTSC and a CID intermediary, Gramheart managed to barge into a meeting between the Grandmaster, McBurn and F. Novartis in the Celestial Globe. Despite the Grandmaster referring to him as their most formidable opponent for their next plan, the two end up agreeing to not interfere with each other's plans for the next two and a half years, Ouroboros Eternal Recurrence Plan and Gramheart's plan to uncover the "possible worlds".
