If the chronicle is to be believed, Óláfr's separation from Lauon enraged her sister—the wife of Rǫgnvaldr and mother of Guðrøðr Dond—who surreptitiously tricked Guðrøðr Dond into attacking Óláfr in 1223. Following what he thought were his father's orders, Guðrøðr Dond gathered a force on Skye—where he was evidently based—and proceeded to , where he is reported to have laid waste to most of the island. Óláfr is said to have only narrowly escaped with a few men, and to have fled to the protection of his father-in-law on the mainland in Ross. Óláfr is stated to have been followed into exile by Páll Bálkason, a "" on Skye who refused to take up arms against him. At a later date, Óláfr and Páll are reported to have returned to Skye and defeated Guðrøðr Dond in battle.
