Nikulás saga leikara

Keren Wick summarised the saga thus:

Nikulás saga leikara ... tells the story of Nikulás, king of Hungary. His foster-father, Earl Svívari, convinces him to stop playing with magic and try to win Princess Dorma of Constantinople as a bride. Svívari makes a secret betrothal with Dorma, contrary to her father's wishes. Nikulás then travels to Constantinople where he poses as a merchant in order to insinuate himself into the Byzantine court. Nikulás meets with Dorma secretly, and the couple escape from Constantinople. Valdimar's Scandinavian mercenaries capture Dorma by employing magic, but Nikulás re-captures his bride, also using magic. The final battle is precluded by Valdimar's accidental killing of his own mercenaries. Valdimar accepts Nikulás, and Nikulás becomes king over Constantinople upon Valdimar's death.^[1]
