Then he pursued and slew Koller's sister Sela, who was a skilled warrior and experienced in roving.
He had now passed three years in valiant deeds of war; and, in order to win higher rank in Rorik's favour, he assigned to him the best trophies and the pick of the plunder.

His friendship with Rorik enabled him to woo and will in marriage his daughter Gerutha, who bore him a son Amleth.
Such great good fortune stung Feng with jealousy, so that he resolved treacherously to waylay his brother, thus showing that goodness is not safe even from those of a man's own house.

And behold, when a chance came to murder him, his bloody hand sated the deadly passion of his soul.

Then he took the wife of the brother he had butchered, capping unnatural murder with incest.

For whoso yields to one iniquity, speedily falls an easier victim to the next, the first being an incentive to the second.
