Callliaste Shanda, the Lillith pictured above is here pictured in her natural form (since that's likely the form the PCs get to fight her in). That is not the form they likely meet her in first. Calliaste communicates with Jurak the Elder via speaking with plants. One of her performed forms is as a dryad consort of the elder treant. Likely, the PCs kill Jurak and earn the enmity of Calliaste that way.
Calliaste is not the sort to seek vengeance by simply attacking the PCs. Instead, she goes among the people of nearby Farholde and begins to stir up trouble using yet another of her forms.
In short, she is a creature of many masks.
