Ertikus
From Tardis Wiki, the free Doctor Who reference
Ertikus was an author of many books on Time Lord history. In his last incarnation, he took a TARDIS to discover the truth from the past, as he was tired of writing and rewriting history books each time something new from the past was uncovered. As travelling back in Gallifreyan history was strictly forbidden, he travelled to Omega's ship to find out the truth. (AUDIO: Omega)
