Luneskon

Luneskon is a female gnoll and the High Shaman of the Moonsteeth gnoll tribe of Rootgarden Marsh. In an adventure hook in the Tal'Dorei Campaign Setting and Tal'Dorei Campaign Setting Reborn, she manages to twist and tangle one of the arcane ley lines in the center of the marsh, ceasing the function of all arcane magic within a radius of one hundred miles.
