Tusktooth mark

The Tusktooth mark, often simply the Mark, is a symbol depicting a face with tusks, usually featuring googly eyes. At first, it appeared as a tattoo made by Jester Lavorre for Lieb as a lifelong reminder of the brush with the Mighty Nein and in the name of the fearsome Captain Tusktooth. More frequently, it appeared as a drawing.
