Helen Keller's Pencil

Origin
Helen Keller was known for being left deaf and blind from a childhood illness, being a great lecturer and her support of leftist causes. She was the teacher of Anne Sullivan, a girl who had near zero comprehension of language. But Helen broke through her isolation within a few months and Sullivan eventually understood more of the world, the two becoming lifelong companions.

Effects
When someone writes the name of a person or group, they can communicate mentally with them, allowing a flow of communication. The downside is that the user turns deafblind for a short while after each use.
