A few pages into Jacques Le Goff's "Intellectuals in the Middle-Ages", I've found mention of demon Titivillus (not to be confused with Titus Livius, a.k.a. Livy, Tite-Live) which I just had to share with you.
Jacques Le Goff holds that as scribal work, a difficult task that produced goods of great intrinsic value, was considered as a way to reduce the time one would spend in Purgatory, while scribing errors due to inattention would conversely lengthen that time. Scribes came to attribute such errors to the influence of Titivillus. Later, he was also described as writing down the idle chatter of monks during the office, as a record of their sins. He then devolved into just one of a family.
I hereby offer you:

Titivillus uses his Obsession power to cause scribal errors. The collection of idle thoughts and words, whether in writing or into his bag are cosmetic effects underling his Betrayal of the Heart power and need not be manifested as actual powers.

Vis: 1 point of Mentem in his bag, parchment or writing implements (or maybe even his ears).
