Verrinnefra was of the signatures on the Declaration of the Alliance of Free Planets after the Battle of Endor. One month later, Indriummsegh signed the Declaration of a New Republic alongside with other important leaders of the Alliance like Leia Organa, Admiral Ackbar, Borsk Fey'lya, and Mon Mothma.
Some months after that, Indriummsegh and the other signatories of the Declaration of a New Republic became the mobile New Republic Provisional Council, with Mon Mothma as the Chief of State. This Inner Council would be active until the capture of Coruscant by the New Republic, 7 ABY, to be replaced by the first New Republic Senate. In 10 ABY, he was one of the signatories of Why Do We Fight the Empire?. Indriummsegh himself was replaced at some point prior to 16 ABY by Senator Rattagagech.
