A Debilitating Sickness

It is good that you've offered to aid us, <name>. Our grunts have fallen sick from drinking contaminated water and I'm missing an ingredient to produce a healing salve. I'm in need of a rare mushroom called drycap. Our foremost orders are to keep our location secret and not risk being spotted while looking for it, or I would go myself. The only place in Hellfire Peninsula where drycap grows is a cave at the Great Fissure, south of here. Be extremely careful if you choose to seek it.
