Pick a glimshroom from the rock face in the southwest of Peacegarden. Linyeve insists that you harvest the fungus with the brightest glow.
Deliver the glimshroom to Linyeve at Hyrstmill.
Glimshrooms are an essential ingredient in the medicine used to treat the disease known as the Creeping Death. With so few conjurers present in Hyrstmill, Linyeve prefers to keep a supply of the medicine on hand to deal with possible outbreaks.
