Tom Meredith

Tom Meredith portrayed Eoghan in The Hunter's Heart. He was the mapmaker's apprentice and was killed by Agravaine after he failed to retrieve the siege plans for him. Agravaine used his dead body to gain access to the vaults. The siege plans were then photocopied by Morgana using a spell. Agravaine returned the original plans to the tunnel so he would not be suspected, especially after Merlin accused him. Arthur fell for it and threatened Merlin with exile.
