Ibram Gaunt, also known as the "People's Hero," is an Imperial Commissar and the commanding officer of the Tanith First and Only regiment of the Astra Militarum, better known as "Gaunt's Ghosts." He later became a Lord Militant, before being appointed the First Lord Executor Militant of the Sabbat Worlds Crusade by Warmaster Macaroth, its second leader.
Gaunt is most notable for leading his regiment in the Sabbat Worlds Crusade which had consumed much of the Sabbat Worlds Sector in the Segmentum Pacificus from 755.M41 onwards. A political favourite of the Imperial Warmaster Slaydo who first commanded the Crusade, Gaunt was given the unusual honour of a regimental command rank of Colonel alongside his Commissar duties on the order of the Warmaster as Slaydo lay on his deathbed.
