The agency will report to Tywin Lannister, Lord of Casterly Rock, and will carry out a wide-ranging reputational and comms brief for the family.
Lord Reyne, director of Reyne Communications, said: "The Lannister family faces significant reputational challenges, including the disputed legitimacy of the Queen Regent’s children and competing claims to the Iron Throne. We will stop at nothing to prevent this vile slander taking root in the minds of the people and we aim to position House Lannister as the rightful rulers of Westeros for a thousand years to come. House Lannister has left us in no doubt as to the price of failure and we do not intend to disappoint them."
House Lannister declined to comment.
