Sar Fareth was a Chaplain of the Word Bearers Legion, during the Great Crusade and received his training under the hand of the Chaplain Xaphen. He later became the Chaplain of Argel Tal's Company, after Xaphen and a number of other Chaplains were sent to secretly create Warrior Lodges within their brother Legions. As the Word Bearers' treachery began to take root though, they were still forced to maintain the veneer of loyalty to the Imperium and continued to bring worlds into Compliance. During one such attempt however, Fareth had his throat torn out by a Human wielding a spear. As his fellow Word Bearers looked on in shock and dismay, a furious Fareth tore apart his killer before he died.
