Came from the Dunlending part of the tree. He found out that while guarding the waters of Anduin, that he was a direct decentant of Freca, who by the way is the first King of Dunlending. It was during this time that Freca was wanting his son, Wulf, to wed King Helm’s daughter of Rohan. King Helm did not want this and this started a war between them. Fearakar found out some time later that the Dunlendings were the true heirs of Gondor. This riled him and he sought out Lostien who was an evil character. Keeping with the history of his people,, he swore that he would have his revenge against the Rohirrim. What a better way to destory the Men of Gondor than to kill the last king. This meant that Fearakar would kill the new King of Gondor, Aragorn, son of Arathorn.
