From the publisher:
When you lose everything, sometimes the path to salvation is madness. A tradition unique to the velin, the grass widows are those who have suffered a great loss, exposed themselves to the information-dense world of Red Truth, and lived to take up the mantel of guardian. Grass Widow is a 10-level advanced class focusing on Red Truth (Dawning Star's unique take on psionics). The pdf includes a full description of the class, 9 new psionic powers, a new poison, two new NPCs, and a write-up of the sacred Hall of Worlds.
