 The saga portrays Aron as a supporter of Bishop Guðmundr, and as in turn receiving the benefits of Guðmundr's numinous assistance.It seems to have been written in the wake of the attempts to have Guðmundr canonised around 1320.It claims that Aron was one of the most famous warriors of his time, becoming an outlaw at the hands of Sturla Sighvatsson, travelling as a pilgrim to Jerusalem, and ending his life at the court of Haakon IV of Norway.
