Mura
From Tardis Wiki, the free Doctor Who reference
Mura was the head guard on Serenity. He framed Escalus for his own crime. He conspired with Auga to get the relics of Malador and overthrow the Elect out of a desire to become the ruler of Serenity. He wanted to kill the Sixth Doctor. He was killed by a Melkur. (AUDIO: The Guardians of Prophecy)
