Hand and Eye of Vecna
The Hand and Eye of Vecna is a cult preoccupied with matters of necromancy. Their political affiliations are mysterious and complex. Van is currently in possession of a powerful spear, “tainted” by their evil magicks.
They have forged powerful necromantic weapons for the Rivan Military, and have now supplied necrotically tainted grain in the name of the Empire. I think they are conspiring with someone high up within Riva City to wage war against the Empire.
