Baragor, later called Ungrim, was a Dwarf who became the first Slayer King of Karak Kadrin.
It is unknown what personal tragedy drove Baragor to take the Slayer oath. Some speculate that it was the death of his daughter, by the claws of the dragon Skaladrak, as she was journeying to Karaz-a-Karak to marry the son of the High King. As both a Slayer and a king, Baragor was torn by different vows. In IC -650, to honour his commitment to the Slayers, he founded the Shrine of Slayers (dedicated to Grimnir) in Karak Kadrin which soon became the centre of the Slayer Cult. Still, his Slayer's vow was not fulfilled when he died in the tunnels below his realm, and it passed on to his son, Dargo, and then down the generations to his living descendant, Ungrim Ironfist.
Baragor took the name Ungrim, meaning "oathbound" or "oath unfulfilled" in Khazalid (the Dwarf language), a named carried by his descendants to this day.
