- "This letter detailing our infantry movements was meant for Lord Damon of House Marbrand. It was sent to Lord Marlin of House Dormund."
- ―Tywin Lannister
Damon Marbrand is the Lord of Ashemark and the head of House Marbrand. He is a bannerman of House Lannister and the father of Ser Addam Marbrand.
Due to Ser Amory Lorch's nigh-illiteracy, a letter from Tywin Lannister to Lord Damon is accidentally sent to Lord Marlin of House Dormund, a vassal of House Stark.
In the books
In the A Song of Ice and Fire novel, little is mentioned of Lord Damon Marbrand. He is not present at his seat during the Battle of Ashemark, with a castellan holding the castle instead.
