Lucien (Spiral Scratch)
From Tardis Wiki, the free Doctor Who reference
Brother Lucien was a monk at a monastery near Wulpit in the 12th century. The people of the village disliked him.
He called Julien and Monica Lamprey the spawn of evil. By preventing them from returning to their home dimension, he was partly responsible for Julien's death. Enraged, she decapitated him. (PROSE: Spiral Scratch)
