Prydon
From Tardis Wiki, the free Doctor Who reference
Lord Prydon was a vampire in a timeline where Rassilon failed to defeat the Great Vampire. He had two children Arcalia and Cassandra. He wanted to meet with Borusa, but Arcalia instead brought him Romana II. He tried to convert Romana into a Vampire; in doing this he could detect which house she came from by the taste of her blood. This conversion didn't work, due to her meeting of the Great Vampire. (AUDIO: Annihilation)
