These strange animals guard ancient knowledge. They are also the keepers of secrets, both their own and those whispered to them by strangers.
They live in places that most people don't even notice. They live in the shadows of shadows, in the reflections of ponds and puddles, or are obscured by patterns in tree bark or sunlight filtered through leaves.
At first sight, their faces appear to be fairly similar. Their faces share a sage world-weariness or melancholy, but it's vital to look at each face closely because each has a very distinct expression.
Some seem sad or anxious, while others are more open and appear curious, amused, or even cheeky.
