The Underbog is home to the last vestiges of natural life left within Coilfang Reservoir that has not been completely stamped out by the Naga incursion. The only Naga presence in this section defends the structure they built to house their hydra god, Ghaz'an. The rest of the Underbog is a natural habitat, home to the most powerful species of animal life in Zangarmarsh. It will give Cenarion Expedition Reputation through Friendly, and through Exalted on Heroic. A Heroic clear will net approximately 2600 rep.
