House Willum

No known record gives the house a seat of its own. Its coat of arms — three silver longswords on sable, with a white chief bearing a dragonbone skeleton — comes from sources treated as semi-canonical rather than the novels themselves.

Like many minor houses of the region, it answers to the Tyrells.

The house declares for Renly Baratheon as soon as he crowns himself king of the Seven Kingdoms. Once Renly is dead, its men fall in with Stannis Baratheon: Josua and his brother fight under his banner at the Battle of the Blackwater.

Defeat leaves them prisoners, and out of that captivity comes a third oath, this time to King Joffrey I.
