Norse sagas telling parts of the story of Augvald include the Saga of Olaf Tryggvason (by both Snorri Sturluson and Oddr Snorrason), the Saga of Half & His Heroes and the Flateyjarbok.
In Sörla þáttr, a short late 14th century narrative from a later and extended version of the Óláfs saga Tryggvasonar found in the Flateyjarbók manuscript, a figure by the name of Göndul appears and instigates the meeting of the kings Hedinn of Serkland and Hogni of Denmark and, by means of seduction and a memory-altering drought, provokes a war between the two.
The stanza (preserved in Snorri Sturluson's Óláfs saga Tryggvasonar) especially praises the jarl for having sent nine princes to Odin (i.e. killed).

His story appears in Heimskringla by Snorri Sturluson, the saga Morkinskinna, and in Óláfs saga Tryggvasonar composed by Oddr Snorrason.
This work is now lost but it is believed to have been an expansion of the Latin Óláfs saga Tryggvasonar written by his monastic brother, Oddr Snorrason.
Composed around 1300 it takes Óláfs saga Tryggvasonar in Snorri Sturluson's Heimskringla as its base but expands the narrative greatly with content from the previous biographies of the king by Oddr Snorrason and Gunnlaugr Leifsson as well as less directly related material.
Theodoric relied heavily on Icelandic sources, possibly including the Oldest Saga of St. Olaf and Oddr Snorrason's Óláfs saga Tryggvasonar.
