It was probably under Ormr's auspices that Arngrímr Brandsson composed the D-version of Guðmundar saga biskups.
Stefán Karlsson has connected the composition of Guðmundar sögur A, B, and possibly C, to the translation of Guðmundur's relics by Bishop Auðunn rauði Þorbergsson in 1314, while Guðmundar saga D was apparently composed by Arngrímr Brandsson for the second translation of Guðmundur's relics by Bishop Ormr Ásláksson in 1344.
