From Fallen London Wiki (Staging)

Sometimes I remember that I'm legally a cat and can do the :3 face in any story and it makes everything a million times better.

Imagine one of the most Paramount figures in London: a renowned inventor and scientist, a philosopher with their own schools of thought, an artist of various mediums, a master thief, a highly-successful businessperson and railroad director, and a paragon of countless skills. Imagine that person doing :3 and meowing. I'm pretty sure even the Masters would be shocked and confused at the sight.

TL;DR: nya~
