Brynaldilath lived on the island of Pendaran and ruled much of the Stallynmere and the Elven Isles. His reign over Pendaran was famous for it’s destruction. Brynaldilath repeatedly burned and ravaged the lands under his control. When the people began to leave Pendaran he began to raid Tarnberyth, Kaylonna and Jotunland.

The neighbouring dragons - Cadolyn, Kaelvaz, Zastek and Rothgar - began to tire of his intrusions into their territories and joined together to kill him. Brynaldilath was killed over Kedawyr Bay. He was the first of the Elder dragons to be slain. Scholars treat Brynaldilath’s death as the last act of the First Age.
