Eprin
From Tardis Wiki, the free Doctor Who reference
Eprin was a man sent by Arbitan to find the keys to the Conscience of Marinus. He found one of the keys on display in what appeared to be a museum in Millennius, but was murdered by Aydan before he could acquire it. Ian Chesterton was subsequently accused of Eprin's murder.
