Beric Dondarrion II

Beric Dondarrion II
Beric Dondarrion II is a renowned guerillia commander who served the riverlands during the first and second clash of kings. He is renowned for his scorched earth tactics during the invasion of the north but most importantly for his actions during the second battle of riverrun.
Background
Beric Dondarrion was the leader of the brotherhood without banners during the war of the five kings, but was usurped by lady stoneheart. Although he was a stormlander by birth, he sided with the Riverlands during the second clash. He also helped House Tully back to it's ancestral seat after the First Clash and reorganized the Brotherhood without Banners to solely serve as a guerilla force.
The second clash
His men threw open the castle gates and let the forces of King Stannis II, who smashed the rebel Lannister forces and routed the entire rebellion. This action proved crucial in the entire battle, and King Stannis II showed his grattitude by giving his daughter's hand in marriage. This gave Lord Beric a place in the Royal family but after the King's brother Renly died without children, a new Lord was needed at Storm's End so King Stannis II gave the Baratheon castle to Beric and his daughter further showing his gratitude for his service at the battle of Riverrun.
