"We were now responsible for aiding the Mallisters at Seagard against the pouting ironborn whenever they got... cheeky."
―Ser Brynden Tully about House Mallister[src]

House Mallister of Seagard is a vassal house that holds fealty to House Tully of Riverrun. Their lands are north of Riverrun, along the west coast of the Riverlands on Ironman's Bay and southwest of the Twins. The castle is near the headwaters of the Blue Fork of the Trident River.

The Mallisters are longstanding enemies of the ironborn, as Seagard was built as a defense against marauders from the Iron Islands.[1]

House Mallister's heraldry consists of a silver eagle on a blue field. Their house words are "Above the Rest."

In the books

In the A Song of Ice and Fire novels, House Mallister is one of House Tully's most loyal vassals. Lord Jason Mallister is noted as both a loyal vassal and also a close personal friend and ally of Lord Hoster Tully. During the Greyjoy Rebellion, the Mallisters defended Seagard from an ironborn assault. While the town and castle were damaged and severe casualties incurred, the ironborn suffered significant losses, with Lord Jason slaying Rodrik Greyjoy in personal combat.

Following the Red Wedding, Lord Jason is one of the few Riverlords, alongside Tytos Blackwood and Brynden Tully, who refuse to yield to the Iron Throne. However, after the Freys threatens to kill his son Patrek, he is forced to surrender. Currently, he and his son are kept prisoners in his own castle.

A slight change is that in the books their sigil is a silver eagle on a purple field, but in the TV series, the field is blue.


  • Lord Jason Mallister, the current head of the family. Currently is held prisoner at Seagard.
    • Ser Patrek Mallister, his eldest son and heir. He attended the Red Wedding and is one of the few guests who were taken alive by the Freys. Currently is held prisoner at Seagard.
  • Ser Denys Mallister, Lord Jason's elderly uncle, a member of the Night's Watch and commander of the Shadow Tower.

No character named "Jaremy Mallister" has been mentioned in the books.
