Dwivir grew up in the Vales, more specifically Grimbeorn's lodge, Grimbeorn's being his father. When he was smaller, Dwivir would go outside the haven and go to Mirkwood, to play, train and meet with his friend, Zagzeroth.

As he trained, the goblins and orcs near the Vales started to fear him, he would be ridding his home of the pesky Sikle flies that lived there, and goblins would attack. He would change into the form of a great black bear and kill them all, so the name of his person would never been told to the goblins, for none went back alive.

When Dwivir was finally let out of his fathers lodge to explore the world, he went to Bree with his friend, Zagzeroth. As he went and travelled around Bree land, he encountered another Beorling, Flokie, who later joined with him to help defend the beorlings.

It was then when he was being ambushed by brigands that he started House Blackfyre, he would need to protect others like him, and his home, the Bearswood. Zagzeroth became his Captain of the Black Claw, his private guard, and Flokie became his general of his army, Raiimond a human trader whom he had met and whom he trusted, became his Master of Trade. More people flooded to his banner of men and beorlings, to become House Blackfyre!
