House Vyrwel of Darkdell is a noble house from Darkdell in the Reach. It is one of the principal houses sworn to House Tyrell.
They blazon their arms with a silver wyvern within a red double tressure on sable.
Lord Vyrwel and his lady wife attended the Whitewalls Tourney. After the Second Blackfyre Rebellion was put down, a man in service to Lord Vyrwel claimed to have been one of the spies of Brynden Rivers. He was promptly killed by a man in service to Lord Costayne.
