Raiding
Heimskringla states that after leaving Novgorod, Olaf raided settlements and ports with success. In 982 he was caught in a storm and made port in Wendland, where he met Queen Geira, a daughter of King Burizleif. She ruled the part of Wendland in which Olaf had landed, and Olaf and his men were given an offer to stay for the winter. Olaf accepted and after courting the Queen, they were married. Olaf began to reclaim the baronies which while under Geira's rule had refused to pay taxes. After these successful campaigns, he began raiding again both in Skåne and Gotland.
