Berek Halfhand is a legendary character in the book with legends saying that he would one day return to the Land. He was a 'half-hand' like Thomas Covenant missing two fingers. Due to this Covenant is seen as Berek's return to the Land.
Berek lived during the Era of the King and Queen and was the strongest and wisest of the Queens champions. Berek kept fighting after the Queens armies fell the only on left who had a hatred for the grey shadow left alive that had come form the east to cause the King's armies to grow hateful themselves. The King eventually fought him single handedly the grey shadow causing Berek's blade to turn aside and the King cleft his hand.
He fled, running for three days till he arrived at Mount Thunder, the mountain spoke to him asking him to pledge himself to the healing of the Earth. He did so and the Fire-Lions rode down the mountain destroying the King and his armies.
