From A Wiki of Ice and Fire
|House Dondarrion of Blackhaven|
|Coat of arms||Sable, semy of four pointed stars proper, a forked lightning purpure|
|Current Lord||Lord Beric Dondarrion|
|Title||Lord of Blackhaven|
The marcher lords' castle is located in the Dornish Marches near the Boneway, controlling the pass to Dorne. Their sigil is a forked purple lightning bolt on black field speckled with four-pointed stars. Their motto is unknown.
The Dondarrion line was founded when a messenger from the Storm King was ambushed by two Dornishmen while riding on a stormy night. An arrow killed his horse and his sword broke when he fell. When he thought he was doomed, a bright purple lightning bolt struck the Dornishmen killing both. The man was thus able to deliver his crucial message on time. For this, the Storm King raised him to lordship, and he became the first Dondarrion.
Ser Arlan and Dunk served Lord Caron and Old Lord Dondarrion when they fought the Vulture King in the Red Mountains three years before the Ashford Tourney. Lord Dondarrion took eight hundred knights and near four thousand foot in the campaign. Dunk recognized Lord Dondarrion's purple lightning at Ashford. Ser Manfred Dondarrion refused to vouch for Dunk's knighthood, even after he repeated the story of the origin of House Dondarrion and their arms as he had heard it in Dondarrion's camp.
At a tourney at Blackhaven, a ten-year old Barristan Selmy entered the lists as a mystery knight. He was eventually unhorsed and unmasked by Prince Duncan Targaryen, earning Barristan the nickname 'Bold'.
