>>23447899"After Balderus' death, Othinus consulted seers on how to get revenge. On their advice, Othinus went to the Ruthenians disguised as a warrior called Roster. There, he was twice turned down by Rinda. He then wrote runes on a piece of bark and touched her with it, causing her to go mad, and disguised himself as a medicine woman called Wecha, who was allowed to see her. She finally fell ill; the disguised Othinus then said he had medicine with which to cure her, but that it would cause a violent reaction. On Othinus' advice, the king tied Rinda to her bed and Othinus proceeded to rape her. From the rape was born Bous, who would later avenge Balderus."
