A Clash of Kings
Vylarr is the commander of the Lannister household guard in King's Landing, which now numbers one hundred men. He is confronted by Tyrion Lannister over where his loyalties lie. He commands the guard that accompanies Tyrion back to the Broken Anvil through the streets of King's Landing.
When Tyrion informs Ser Cleos Frey of his terms for peace, he commands Vylarr to escort Cleos back to Riverrun, taking all of the Lannister guardsmen with him. After their arrival at Riverrun, there is an effort to free Ser Jaime Lannister from his cell by the men who came as part of the Lannister guard that Vylarr commanded. Temporarily free, Jaime attempts to flee but is soon subdued. Seeing Jaime attempting to break out, some of the Lannister guardsmen rush to aid him but are also subdued. Those not killed in the attempt are imprisoned.
