A satyr known as Vyletongue has corrupted the caverns of Maraudon, stunting the growth of many of the plants inside. Take this vial, adventurer. Fill it at the orange crystal pool found inside the caverns; the coating inside the vial will counter the toxins, turning it into a healing agent. Find the Vylestem vines inside the orange caverns, and use the purified liquid on them. The corruption will be purged from the plant, but do know that Vyletongue will still control it. He may use it against you...
