Most of the information that we have about Jaren Ward comes from the accounts of Shin Malphur in The Last Word's Grimoire Cards.
Malphur was born in Palamon, a small town in the wilds ruled by the corrupt Magister Loken,1 and was still a child when Jaren Ward first visited.2 After being threatened with death by Loken, Jaren Ward killed the corrupt ruler, liberating the town.3
Some time later Dredgen Yor visited Palamon. The events that unfolded are not well documented, but the town was left in ruins.4
Ward attempted to guide nine people, including Malphur, from Palamon to the City. Three were killed during the journey.5
Ward's Ghost gave Malphur The Last Word, and chose him to be his next Guardian.5
Years later Shin Malphur met Dredgen Yor at Dwindler's Ridge, where Malphur finally ended Yor's reign of terror.4
